How to Upgrade to Business Class: Bid Odds, Real Costs, and When a Sale Fare Wins

Last updated 20 July 2026 · Fare data updated 20 July 2026, from 250 verified business class alerts

There are 3 ways to upgrade to business class: bid in the airline's upgrade auction, pay a fixed upsell at check-in, or skip the upgrade and buy a business class sale fare outright. The auction is the popular route and the weakest: reported winning bids on London to New York run £500 to £700 each way, none guaranteed, while across the 250 business class fares we verified in the last 12 months the median was 53% below the airline's quoted standard price (EUR fares, measured only where the alert quoted a standard fare).

How do business class upgrades actually work?

Airlines sell the same flat bed through 3 doors. The first is the upgrade auction: you hold an economy or premium economy ticket and offer money to move up. More than 50 airlines run auction-style programmes, according to AFAR, most on the same white-label platform from Plusgrade, a Montreal travel-tech firm, as Prince of Travel explains.

The second door is the fixed-price upsell. Emirates runs no auction at all: NerdWallet notes "there is no bidding option at this time", and its upgrades are fixed-price cash or Skywards miles, even at the gate. Air France and KLM work the same way, showing a personalised cash or miles price at online check-in when premium seats remain, per KLM's own pages. Miles are a variant of this door: Lufthansa's Miles & More prices Upgrade Awards at roughly 10,000 to 85,000 miles per segment, per its programme pages.

The third door is not an upgrade at all: buy business class outright when the route goes on sale. That is the door we watch: the rest of this guide prices the auction honestly against it.

The free upgrade at the desk is a myth

Going puts it plainly: "Airlines rarely grant free upgrades simply for asking", and free moves are "typically reserved for elite frequent flyers or those affected by overbooked flights", ranked by status, fare class and booking history. Charm at the desk is not a strategy.

How does bidding for an upgrade work?

The mechanics are near-identical everywhere, because the platform is. You enter your booking reference on the airline's bid page, set an offer between a shown minimum and maximum, and leave card details; the card is charged only if the bid wins, as AFAR and The Points Guy describe. Windows typically open 2 to 7 days before a flight and close as few as 5 hours before it, per AFAR. Decisions land 24 to 72 hours before departure, and an accepted bid is non-refundable unless the airline cannot deliver the upgrade, per The Points Guy and Virgin Atlantic's terms.

Two structural details decide the economics. Bids are per flight and per passenger: a return means 2 separate bids, and Virgin Atlantic's terms confirm every passenger on a booking must be upgraded together. Your bid range also depends on your original fare class: Prince of Travel reports cheaper tickets are shown higher ranges.

What are the odds of winning an upgrade bid?

Nobody outside the airline knows. No airline publishes win rates: AFAR notes carriers "don't readily offer insight about how many other people have submitted bids and for what amount", and Prince of Travel is blunter: "Airlines don't publicly disclose winner selection formulas." Percentages circulate online; none we found were attributed to a dataset, so we will not print one.

What we can explain is why the odds are structurally low. Auctions monetise unsold premium space: Prince of Travel describes the Plusgrade model as a way for airlines "to generate ancillary revenue from unsold space". Revenue management tries to sell every seat at full price first; your bid is only considered when seats remain unsold near departure, which is why decisions land so late. Virgin Atlantic's own terms name the factors: the bid amount is only one, alongside seats left in the next cabin, passengers in the bid, and when it was received. On a busy route there is often nothing left to auction.

What does a winning bid really cost?

Published and reported numbers run higher than most bidders expect. Head for Points reported British Airways ranges of £520 to £675 one-way just to move from premium economy to Club World on JFK to LHR, and £1,170 to £1,520 from Club World to First. PointsFeed's Virgin Atlantic data points put most winning Premium to Upper Class bids at £500 to £700 one-way; its single economy to Upper Class example was $955. Travel-Dealz found a Lufthansa myOffer minimum of €460 for premium economy to business. At the cheap end, Going staff have seen $200 to $500 bids accepted from economy to business on long-haul flights.

Then the multipliers arrive. A bid covers one direction: a return doubles it. It is per passenger too, and Virgin Atlantic upgrades every passenger on a booking together, so a couple doubles it again. The Points Guy's rule of thumb is to bid 20 to 40% of the fare gap, slightly above the minimum; one of its contributors won economy to business for €450.

What the winning bid leaves out

A won bid is not a business class ticket at several carriers; it is a business class seat on an economy ticket. Virgin Atlantic's terms state that points and tier points "will be based on the class of ticket that you originally purchased, and not the upgraded cabin"; Etihad credits the original class too, per Upgraded Points. On British Airways, Head for Points reports lounge access is granted but the baggage allowance is not uplifted, and the fee is non-refundable even if the flight is cancelled. TAP strips the most: win a bid inside 36 hours and you get the seat only, no lounge, no fast track, no extra baggage, per TAP's own pages. This is not universal: Travel-Dealz reports a successful Lufthansa bid earns miles in the new booking class. And per Prince of Travel, the fee counts nothing towards elite qualifying spend.

Does economy plus a winning bid beat a business class sale fare? The maths

Run the New York numbers, in pounds throughout. Reuters and US News put average transatlantic economy returns at $817 in summer 2025, and momondo booking data has New York returns at $538 to $566 in the cheapest months; a typical London to New York economy return works out around £450 to £550. Add 2 winning bids at the reported £500 to £700 each way and the total is roughly £1,450 to £1,950, decided as late as 6.5 hours before a British Airways departure. Our verified sale fares to New York started at £1,484 return from London, median £1,746 (11 route prices). The maybe costs about the same as the certainty.

The euro side is stronger still. Across 21 business class fares to New York in the last 12 months, the lowest verified price was €1,209 from Dublin (DUB) on British Airways, against a €3,000 quoted standard fare; the median EUR route price was €1,799. Where a standard fare was quoted, the median discount was 55% (n=19), and the largest single saving was €2,288 on SAS in March 2026. A New York fare appeared in 12 of 13 calendar months, roughly one every 17 days.

The Southeast Asia example: Bangkok

Bangkok makes the same point in euro. It appeared in 59 of our alerts in the last 12 months, nearly all business class, with verified prices from €1,379, a median of €1,985, and a median 47% off where a standard fare was quoted and beaten (n=56). Two winning bids at even the cheapest documented European levels, the €450 win reported by The Points Guy and Lufthansa's €460 minimum, add roughly €900 to €920 to a return. To beat our €1,985 median, the economy return must cost under about €1,065; to beat our €1,379 floor, under about €460. And that assumes both bids win, on a corridor where Milan (MXP) to Bangkok alone went on sale 30 times in 12 months, never above €3,335.

For pound-based readers: Skyscanner lists London to Bangkok economy returns from £338 and Thai Airways non-stop from £915, per their own route pages; our verified GBP business class prices to Bangkok ran from £1,498, median £2,041. The gap between economy and a verified sale fare is real, but smaller than the brochure suggests, and it is a price you can actually book.

When is bidding still worth it?

Bidding deserves a fair hearing, because there are 4 situations where it genuinely wins.

First, when you already hold the ticket. A sale fare is bought before a trip exists; if the flights are already booked, the auction is one of the few doors left, and a bid near the minimum costs nothing to place unless it wins.

Second, on undersold flights. The auction clears unsold space, so low-demand departures are where low bids land. Going staff have seen $200 to $500 bids accepted on long-haul flights, and TAP wins have been reported from $200. A €450 winning bid on a half-empty cabin beats any sale fare on that flight.

Third, when you can bid with points. SAS accepts EuroBonus points, TAP accepts Miles&Go miles outside the final 24 hours, and Etihad accepts Etihad Guest miles. If your points are otherwise idle, a points bid risks no cash at all.

Fourth, when you only want one leg. Sale fares are returns; bids are per flight. If all you want is a flat bed on the overnight leg home, one bid on that sector is half the auction cost. Follow The Points Guy's rule, 20 to 40% of the fare gap, and check Going's tip first: the outright upgrade price is sometimes at or below the minimum bid.

Why does waiting for a sale usually win?

Because the sale fare removes the two things the auction sells you: uncertainty and a stripped product. A bid is decided in the final 24 to 72 hours, sometimes 6.5 hours before departure; you pack for economy and hope. A sale fare is confirmed the moment you book, and 94% of our fares were still bookable 3 or more months after the alert, 74% at 6 or more months, based on the availability calendars in our alerts. You plan the trip in business class rather than gamble your way into it.

Frequency is the second reason. We verified 250 business class fares in the last 12 months: 4.8 a week, 17 to 25 every month, never more than 6 days without one. New York appeared roughly every 17 days; our busiest Bangkok pairs returned at median gaps of 7 to 15 days. You are waiting days or weeks, not seasons, for a ticket that earns and boards as business class.

Price is the third. The average EUR fare we sent cost €1,636 against a €3,510 quoted standard fare, a saving of €1,874, with a median discount of 53% (EUR, n=201; measured only on fares that quoted a standard fare and had a priced route below it). GBP fares averaged £1,842 against £3,543, median 49% off (n=93, same convention). One concession: of the 70 fares where refundability was recorded, exactly 1 was refundable, so treat our fares as non-refundable. But an accepted bid is non-refundable too, and the fare asks only modest flexibility: 55% of our fares needed just a 2 to 3 day minimum stay.

How we built this

Frequently asked questions

Is bidding for a business class upgrade worth it?

Sometimes, but not as a plan. Bid when you already hold the ticket, the flight looks undersold, you bid near the minimum, or you can bid with points on SAS, TAP or Etihad. As a strategy it is weak: no airline publishes win rates, decisions land 24 to 72 hours out, and economy plus 2 winning London to New York bids runs roughly £1,450 to £1,950 against our verified sale fares from £1,484.

How much should I bid for a business class upgrade?

The Points Guy suggests 20 to 40% of the fare gap, slightly above the shown minimum. Reported wins: £500 to £700 one-way on Virgin Atlantic per PointsFeed, £520 to £675 premium economy to Club World on British Airways per Head for Points, and $200 to $500 long-haul wins seen by Going. Check the outright upgrade price first: Going notes it is sometimes at or below the minimum bid.

What are the odds of winning an upgrade bid?

No airline publishes win rates, and selection formulas are not disclosed, per AFAR and Prince of Travel. Virgin Atlantic's terms say the bid amount is only one factor, alongside unsold seats, passengers on the bid, and when it was received. Auctions only clear seats that failed to sell at full price, so on busy flights there is often nothing to win.

Does a winning bid include lounge access, extra baggage and miles?

It varies by airline. British Airways grants lounge access but does not uplift baggage, per Head for Points. TAP bids won inside 36 hours include no lounge, no fast track and no extra baggage. Virgin Atlantic and Etihad credit miles on the original class; Travel-Dealz reports Lufthansa credits the new booking class.

Is economy plus an upgrade bid cheaper than a business class sale fare?

Usually not by much, and it is never guaranteed. A London to New York economy return of about £450 to £550 plus 2 winning bids at £500 to £700 each way totals roughly £1,450 to £1,950. Our lowest verified sale fare on the route was £1,484 return, median £1,746, confirmed at booking. To Bangkok, verified fares ran from €1,379, median €1,985.

Which airlines let you bid for a business class upgrade from Europe?

British Airways, Lufthansa, Virgin Atlantic, TAP Air Portugal, SAS, Etihad and Aer Lingus run bid programmes, along with Air Europa, Brussels Airlines and Edelweiss, per AFAR. Emirates, Air France and KLM run no auctions: they sell fixed-price cash or miles upgrades at check-in instead.

Can I upgrade to business class for free by asking at check-in?

Rarely. Going reports airlines seldom grant free upgrades for asking; free moves go to elite frequent flyers or passengers on overbooked flights, ranked by status, fare class and booking history. Without status, the realistic paths are a bid, a paid upsell, miles, or a sale fare bought outright.

The bottom line

Upgrading by auction means bidding a reported £500 to £700 each way for a seat that is not confirmed until the final hours, at odds no airline will publish. Bid if you already hold the ticket, the cabin looks empty, or your points are idle. Otherwise the arithmetic points one way: our 250 verified alerts arrived 4.8 times a week, at a median 53% below the quoted standard fare where one was quoted, and 94% were still bookable 3 or more months out. The surest upgrade is the one you book as a fare.
