Air India's Upgrade+ programme lets economy passengers bid for Business Class seats on eligible flights. It's a post-booking email-triggered flow with a bid range set by the airline. Your miles still accrue at the original booking class even after a successful upgrade. The window to bid opens around 4–6 weeks before departure and closes roughly 24–48 hours before the flight.
TL;DR — the short answer
Air India Upgrade+ is an upgrade-bidding programme where economy class passengers can submit a cash bid for a Business Class seat on eligible flights. The bid range — a minimum and maximum the airline sets — varies by route and how full the Business cabin is. You'll receive an email invitation to bid roughly 4–6 weeks before departure; the bid window closes around 24–48 hours before the flight. Payment is only charged if the bid is accepted. Crucially — and this is the detail most people miss — your Flying Returns miles accrue at your original booking class (economy), not at the Business Class rate, even after a successful Upgrade+. You flew economy on paper, regardless of which seat you sat in. Verify all current terms on airindia.com — the programme details have been updated since the Vistara merger.
What is Upgrade+ and how does it work at a high level?
Upgrade+ is an automated upgrade-revenue optimisation tool — the kind that large airlines globally call 'bid upgrade' systems (similar to what Singapore Airlines, Lufthansa and Emirates run). Air India rolled it out initially on international routes and has expanded to some domestic routes, though as of 2026 it's primarily relevant for long-haul international flights where the economy-to-business price gap is significant.
The mechanics: Air India knows roughly how many unsold Business Class seats will exist on a given flight. Rather than let those go empty (or wait for last-minute full-fare buyers, who are increasingly rare), they invite eligible economy passengers to bid above a minimum price. The airline accepts the highest bids that fill the available seats, usually in the final 24–72 hours when the picture is clear. You get Business Class for less than the published fare; the airline gets revenue on a seat that would have otherwise flown empty.
It's not a lottery and it's not a cheap deal guaranteed — a competitive bid on Delhi–London can still be in the range of tens of thousands of rupees. But it's typically considerably less than the outright Business Class fare difference, which makes it interesting for occasional travellers who'd never pay for Business outright.
Who is eligible to bid — and when does the invitation come?
Eligible passengers are those who booked an eligible economy fare on a flight where Air India has Business Class capacity to upgrade into. Not all flights and not all fare types participate. Key eligibility factors:
- Fare type: Flex economy fare passengers are automatically entered into the Upgrade+ pool (the enrolment is included in the fare). Classic and Value economy passengers can also receive an invitation, but it's not guaranteed — Air India's system appears to prioritise Flex ticket holders when Business inventory is limited.
- Flight eligibility: International routes with Business Class cabins are the main arena. Air India's widebody network — flights to London Heathrow, New York JFK, Chicago, Singapore, Melbourne, Frankfurt, Paris CDG — are the most common Upgrade+ eligible routes. Some domestic routes with configured Business Class cabins (Delhi–Mumbai, Delhi–Bangalore on specific aircraft) also participate, though the frequency and bid ranges are different.
- Invitation timing: The email invite typically lands in your booking email inbox around 4–6 weeks before departure. Check your spam folder — Air India marketing emails have an unfortunate habit of going there. You can also log into your airindia.com account and check the 'Manage Booking' section, which shows Upgrade+ eligibility if it applies to your flight.
If you booked through an OTA and your email at booking differs from your Flying Returns email, set up your Flying Returns number in the booking — the system needs to know who you are to send the invite.
How to place a bid: the step-by-step
When the invitation email arrives, here's the flow:
- Click the Upgrade+ link in the email (or access it via 'Manage Booking' on airindia.com). You'll be taken to the Upgrade+ bid page, which shows your flight, the Business Class cabin details, and the bid range for your route.
- Review the bid range. Air India sets a minimum bid and a suggested range (or maximum). The minimum is the floor below which no bid is considered. Bidding the minimum is the budget-conscious play — it may or may not win. Bidding higher increases your chances but eats into the saving versus buying Business outright.
- Enter your bid amount and provide payment details. Important: your card is NOT charged at this point. It's only authorised/held pending the outcome.
- Wait for confirmation. The result typically comes 24–48 hours before departure via email — either a confirmation that your bid was accepted (the payment is now charged, your boarding pass reflects Business Class) or a decline. If declined, no charge is made.
- Check your boarding pass at web check-in. If your upgrade was accepted, your seat assignment will be in the Business cabin when you check in. If you've somehow not received the confirmation email, check the Manage Booking page directly.
One nuance: if Air India changes the aircraft or the Business cabin configuration after you've bid (not rare on Air India given ongoing fleet reshuffles in 2026), they may revise or cancel bids. Keep an eye on your email in the 72 hours before departure.
What bid amount actually wins? Bid strategy in practice
I want to be honest here: there's no public formula for what bid wins, and Air India doesn't publish acceptance rates. Some observations from the programme and general industry practice:
- Bidding just above the minimum works occasionally — particularly on routes with lower demand for Business (some fifth-freedom routes, off-season dates).
- On peak routes (Delhi–London in peak summer, Mumbai–New York around Diwali), minimum bids rarely win. The accepted bid tends to be closer to the midpoint of the range or above.
- The accepted bid amount relative to the Business Class fare gap varies enormously by route. On a long-haul flight where Business is priced at ₹3–4 lakh and economy is ₹60,000–₹80,000, a winning bid might be in the ₹30,000–₹80,000 range — still potentially compelling. But these are rough historical impressions, not guarantees.
- Do not bid an amount you'd resent paying if accepted. The card is charged when the bid wins; there's no cancellation once accepted.
The pragmatic approach: decide what the upgrade is worth to you personally (comfort on a 9-hour flight, lounge access, the lie-flat seat), and bid that. Treat it as paying for the experience, not gaming a system.
Miles accrual after a successful Upgrade+ — the important detail
This is where people get caught out. Even after a successful Upgrade+ upgrade, your Flying Returns miles accrue at your original booking class. If you bought an economy Value fare, your miles accrue at the economy Value earning rate — not at the Business Class earning rate, which would typically be 150–200% of the economy rate or more depending on the route and class of service.
The rationale from the airline's perspective is simple: you paid an economy fare plus an upgrade fee, not a Business Class fare. The ticket was issued in economy. The mileage accrual follows the ticket class.
This matters most to Flying Returns members who are trying to accrue miles towards a higher tier status. If you're close to a status threshold — say, trying to reach Silver or Gold — a successful Upgrade+ that gets you into Business physically doesn't give you the mileage credit of a Business ticket. Factor this into whether Upgrade+ makes sense versus using your existing miles to book a Business Class award or simply buying a Business fare directly.
For everything Flying Returns-related, the source of truth is the programme terms on airindia.com. The programme went through significant changes during the Club Vistara merger process, and some redemption rates have been adjusted since.
Is Upgrade+ worth it? And when does it make sense?
On long-haul flights (8+ hours), Business Class isn't a luxury — it's the difference between arriving functional and arriving wrecked. If you're flying Delhi–New York for a business trip or London–Mumbai to be at a family occasion, the bid for a lie-flat seat has real value. On a 4-hour flight to Dubai? Probably less so, though the lounge access and extra baggage are still useful.
Where Upgrade+ is most compelling: off-peak international routes where Business cabin fill is lower, you can bid modestly and have a reasonable chance. On peak summer Delhi–London or peak Diwali Mumbai–New York, the Business cabin tends to fill with paid Business passengers and Upgrade+ bids need to be aggressive to win.
The other scenario where it works well: you booked a Flex fare anyway (for refundability reasons), your Upgrade+ bid is automatic, and you've got nothing to lose by putting in a reasonable number. If it wins, great. If not, you're still in economy with a free seat choice and full flexibility.
Compare fares across carriers on FlightGPT first — sometimes a direct Business Class fare on Air India is closer in price to economy than you'd expect on off-peak routes, particularly with advance purchase. Also see our guide on Air India's fare tiers for the full picture of what each economy tier includes before deciding whether Upgrade+ applies to your booking.
Frequently asked questions
When does the Air India Upgrade+ bid invitation arrive?
The email invitation typically arrives around 4–6 weeks before departure. The bid window closes approximately 24–48 hours before the flight. Check your spam folder if you're not seeing it — also check 'Manage Booking' on airindia.com directly, which shows Upgrade+ eligibility if your flight qualifies. Verify timing on airindia.com as the programme parameters are updated periodically.
Am I charged immediately when I submit an Upgrade+ bid?
No — Air India places an authorisation hold on your card when you submit the bid, but the charge only goes through if your bid is accepted. If your bid is declined, no amount is charged and the hold is released. Accepted bids are typically confirmed 24–48 hours before departure via email.
Do Flying Returns miles accrue at Business Class rate after a successful Upgrade+?
No — this is a common misconception. Miles accrue at your original booking class (economy), not at the Business Class earning rate, even after a successful Upgrade+. Your ticket was issued in economy; the mileage system follows the ticket. If miles accrual is important to you, factor this in when deciding whether to bid. Confirm current accrual terms on the Flying Returns page at airindia.com.
Can Value or Classic fare passengers also bid on Upgrade+?
Yes — Upgrade+ invitations can go to Value and Classic fare economy passengers, not only Flex. Flex fare includes complimentary Upgrade+ enrolment; Value and Classic passengers may receive an invitation depending on the route and Business Class inventory. Flex ticket holders may be prioritised when Business inventory is limited.
Which Air India routes are eligible for Upgrade+?
Primarily long-haul international routes with configured Business Class cabins — London, New York, Chicago, Singapore, Melbourne, Frankfurt and similar. Some domestic routes with Business cabins (Delhi–Mumbai, Delhi–Bangalore on specific widebody configurations) also participate. Not all flights on eligible routes participate on every departure — check Manage Booking on airindia.com or wait for the invitation email to confirm your specific flight.
How much should I bid to maximise chances of winning?
There's no public formula. Bidding near the minimum wins on lower-demand routes and off-peak dates; on peak routes (summer Delhi–London, Diwali season transatlantic), you typically need to bid in the upper half of the range to be competitive. A practical approach: decide what the upgrade is genuinely worth to you for comfort and convenience, and bid that amount. Don't bid an amount you'd resent paying if accepted.
