Air India's Maharaja Club lets you upgrade a confirmed economy booking to business class using accrued miles — including points converted from HDFC, ICICI and SBI credit cards. The key tool is Upgrade+, available on the Air India website, and the online upgrade window typically closes around 12 hours before departure.
TL;DR — can you actually upgrade on Air India with miles?
Yes — Air India's Maharaja Club loyalty programme lets members use miles to upgrade a confirmed Economy ticket to Business Class on most Air India-operated flights. The tool you use is called Upgrade+, accessible after logging into your Maharaja Club account on the Air India website. The upgrade window opens some time after booking and typically closes online around 12 hours before departure (you can sometimes try at the airport check-in desk after that, subject to availability). Miles required vary by route and cabin availability — check the Maharaja Club award chart on the official site for current rates, as these numbers change. You can also convert points from certain Indian bank credit cards into Maharaja Points to top up your balance.
What is the Upgrade+ tool and how does it work?
Upgrade+ is Air India's self-serve upgrade mechanism for Maharaja Club members. Here is the flow as it works in 2026:
- Book a qualifying Economy fare. Not all economy fare classes are eligible — deeply discounted promotional fares (usually the lowest published bucket) are often excluded. When booking, look at the fare rules or check Air India's Maharaja Club redemption conditions page. Flexible economy fares and mid-tier economy buckets are generally upgrade-eligible.
- Log into your Maharaja Club account on the Air India website and go to 'My Bookings'. The Upgrade+ option will appear alongside the PNR if your fare class and route are eligible, and if Business seats are available for upgrade.
- See the miles required and confirm. The system shows you exactly how many Maharaja Points the upgrade costs for that specific flight. Confirm, and the miles are deducted instantly. Your booking updates to a Business Class PNR.
- Online window closes roughly 12 hours pre-departure. After that, your only shot is at the airport — check-in desk or upgrade desk — where mileage upgrades are possible but not guaranteed, and depend entirely on the load factor. I have had this work at CSIA Mumbai exactly once and fail three times, so don't bank on it.
One practical tip: the Upgrade+ tool will only show you the option when Business inventory is actually released for mileage use. Air India controls how many seats it releases for upgrades on each flight — popular routes (DEL-LHR, BOM-JFK, DEL-SFO) often have very tight upgrade availability, especially in peak summer and winter seasons. On thinner routes and off-peak dates, availability tends to open up. Check early and check often.
How do HDFC, ICICI and SBI points convert to Maharaja Points?
This is where it gets genuinely useful for Indian cardholders — and also where you need to verify numbers on the respective bank's website because conversion rates and terms get tweaked periodically.
HDFC Bank (SmartBuy / Diners Club / Regalia / Infinia): HDFC allows points transfer to Maharaja Club via the SmartBuy portal or the Rewards Catalogue. The general principle is that HDFC reward points convert to Maharaja Points at a fixed ratio — historically in a range that makes long-haul upgrades feasible if you have a healthy balance on a Diners Club Black or Infinia card. HDFC has also run promotional transfers at enhanced rates during Air India sale periods. The exact ratio: check the HDFC SmartBuy portal under 'Airline Transfer Partners'.
ICICI Bank (Emeralde / Sapphiro / Rubyx): ICICI's PAYBACK points and credit card reward points can transfer to Maharaja Club, though ICICI's programme structure changed through 2024–2025. Verify current transfer availability and ratio on the ICICI Rewards portal — don't rely on what you read a year ago.
SBI Card (Elite / Prime / Miles Elite): SBI Card's Miles Elite is co-branded with Air India and directly earns Maharaja Points on spend. SBI's general reward points (on Elite, Prime, etc.) also transfer to airline partners but the SBI accelerated-reward cut from March 2025 reduced earn rates on certain categories — specifically capping points on utility and insurance payments. If you are SBI-heavy, recalculate your effective earn rate post-March 2025 before planning a big upgrade redemption. Details on the SBI Card website under 'Rewards FAQ'.
Transfer lead time is real: point transfers from banks to Maharaja Club typically take 5–7 working days (sometimes up to 10), not instantly. If you are targeting an upgrade on a specific flight, initiate the transfer well before the upgrade window opens. Do not cut it close.
Which Air India routes and cabins can you upgrade on?
Maharaja Club upgrades generally work on Air India-operated flights — the airline's own equipment on domestic (Air India-marketed routes) and international sectors. A few things to know:
- Codeshare and partner flights: If your Air India ticket number actually puts you on a Star Alliance partner aircraft (Lufthansa, United, Singapore Airlines), Upgrade+ typically does not apply. You need to be on an AI-designator flight operated by Air India's own equipment. Check the operating carrier on your ticket.
- Air India Express: This is Air India's low-cost subsidiary — single-class cabin, no business class, so upgrades do not apply here.
- Domestic upgrades: Air India does operate business class on some domestic trunk routes (Delhi–Mumbai, Delhi–Bengaluru, Delhi–Chennai, Mumbai–Bengaluru). The upgrade miles requirement on domestic is much lower than international. These can genuinely be good value if you want the lounge + lie-flat seat experience on a busy morning IndiGo-dominated route.
- International widebody routes: Delhi–London (LHR), Mumbai–London, Delhi–San Francisco, Delhi–New York, Mumbai–Chicago — these are the premium upgrade targets. Business availability for miles is tight on these but not impossible in the shoulder months (February–March, September–October).
Is upgrading with miles actually worth it on Air India?
Depends on what you value. Air India's Business Class on the A350 and 787 Dreamliner on long-haul routes — the fully flat bed, the Michelin-tie-up meal service, the genuine improvement in sleep quality on a 9-hour DEL-LHR sector — is genuinely excellent, and the cash price of a Business ticket on that route is several times the economy fare. If you have accumulated Maharaja Points from bank transfers and natural flying, using them to upgrade a discounted economy ticket into Business can deliver outsized value compared to just burning points on merchandise or flight redemptions at low value.
The calculation breaks differently when you are comparing against budget carriers on domestic. An Air India Business upgrade on DEL-BOM makes less logical sense when IndiGo gets you there in the same 2 hours for a fraction of the price and there is no lie-flat to speak of anyway.
My honest take: use Maharaja Points for long-haul international upgrades or redemptions. The domestic upgrade value proposition is real but niche. And watch for Air India's periodic 'Upgrade Weeks' — the airline occasionally runs promotional periods with lower mile requirements or enhanced partner-point transfer ratios. Sign up for Maharaja Club emails so you catch those. Search Air India flights on FlightGPT to compare the cash fare gap between Economy and Business before deciding whether a miles upgrade is the smarter play.
Step-by-step: Upgrading your Air India booking right now
Here is a condensed checklist:
- Make sure you are enrolled in Maharaja Club and your PNR has your membership number attached. Orphaned PNRs (booked without the membership number) can sometimes be linked retroactively, but it is a support call.
- Check your Maharaja Points balance at maharajaclub.com. If you need to top up, initiate the bank transfer immediately — allow 5–7 working days.
- Log into Air India, go to Manage Booking → Upgrade+. The tool tells you if your fare class is eligible and shows the miles cost.
- Compare: is the miles cost reasonable given what you estimate each point is worth? A rough benchmark — though not a hard rule — is that Maharaja Points used for Business upgrades should ideally yield value above ₹0.50–₹0.80 per point. Below that, you may be better off burning points for something else or simply watching for a Business Class sale fare.
- Confirm the upgrade. Screenshot the confirmation. Your seat selection will need to be redone in Business Class seating.
- If the online tool shows no availability, check again 48 hours before departure — Air India sometimes releases additional upgrade inventory close to departure as load factors clarify.

Common upgrade pitfalls to avoid
A few things that catch people out:
- Wrong fare class: The cheapest economy fares (often labelled as 'Saver' or the lowest published bucket) are frequently ineligible for upgrades. Always check fare class upgrade eligibility before buying a ticket you plan to upgrade.
- Points expiry: Maharaja Club points expire if there is no earning or redemption activity within a fixed window (verify the current rule on the Maharaja Club site — it has changed). If your account has been dormant, a small transaction can reset the clock.
- Transfer lag timing: I have seen travellers transfer bank points two days before a flight and then discover the transfer has not credited yet. The airline's upgrade tool will not show the miles. Transfer early.
- DCC at partner hotel lounges: Nothing to do with upgrades, but while you are in the Air India lounge — always worth a reminder to decline dynamic currency conversion on any USD/EUR charges.
Frequently asked questions
How many Maharaja Club miles do I need to upgrade economy to business class on Air India?
The miles required depend on the route, the fare class of your original economy booking, and how many upgrade seats Air India has released on that specific flight. Short domestic sectors cost significantly fewer miles than a Delhi–London long-haul upgrade. Check the current award chart at maharajaclub.com or use the Upgrade+ tool in Manage Booking — it shows the exact cost for your PNR.
Can I transfer HDFC Infinia or Diners Club Black points to Maharaja Club?
Yes, HDFC Bank credit card reward points can be transferred to Air India Maharaja Club via the HDFC SmartBuy portal. The transfer ratio and minimum transfer amount: verify on the HDFC SmartBuy 'Airline Partners' page, as these change. Allow 5–7 working days for points to credit to your Maharaja Club account after initiating the transfer.
What is the deadline to upgrade online using Maharaja Club miles?
The Upgrade+ online tool typically closes around 12 hours before scheduled departure. After that, you can try at the airport check-in or upgrade desk, but mileage upgrades at the airport are subject to seat availability and are not guaranteed. Do not leave it to the last minute — online is your best shot.
Does the SBI Miles Elite card earn Maharaja Points directly?
Yes. The SBI Card Miles Elite is a co-branded Air India card that earns Maharaja Points on everyday spend. Note that SBI reduced accelerated earn rates on certain spend categories (utility payments, insurance premiums) from March 2025. Check the current earn structure on the SBI Card website before relying on older figures.
Can I upgrade an Air India Express ticket using Maharaja Club miles?
No. Air India Express operates as a low-cost carrier with a single economy cabin — there is no business class product to upgrade into. Maharaja Club upgrades apply only to Air India-operated mainline flights that have a Business Class cabin.
What if the Upgrade+ tool shows no availability on my flight?
Air India controls how many seats it releases for mileage upgrades on each flight. If no inventory is available now, check again 48–72 hours before departure — airlines often release additional upgrade seats late as the flight fills and unsold business cabins become clearer. You can also ask at the airport check-in desk, though this is less reliable.
