Quick answer: You don’t have to book Business Class from the start to fly in it. Finnair offers four upgrade paths: paying cash, using Avios, redeeming Finnair Plus Upgrade Benefits, or requesting an upgrade at the airport if seats remain unsold. There’s no fixed price. What you pay depends on your route, fare, and how close to departure you’re upgrading.
A Finnair Business Class upgrade lets eligible passengers enjoy a noticeably more comfortable trip without paying for a Business fare upfront. Depending on your booking and what’s available, you can upgrade using cash, Avios, Finnair Plus Upgrade Benefits, or an airport upgrade on the day of travel.
Availability, eligibility, and price all shift based on your route, fare type, and how much Business Class inventory is left, so it helps to understand how the system actually works before you request one.
Why Finnair Business Class Stands Out
Finnair redesigned its long-haul Business Class around comfort, privacy, and Nordic design rather than a traditional recliner. Depending on your upgrade type and aircraft, it can include:
- The Collins Aerospace AirLounge seat on long-haul aircraft
- Direct aisle access in a 1-2-1 cabin layout
- A fully flat sleeping surface
- Priority check-in and boarding on eligible upgrades
- Lounge access where included
- Premium dining and beverages
- Additional baggage allowance, depending on ticket
- Complimentary Wi-Fi on eligible flights
The AirLounge Seat: What Makes It Different
Finnair’s AirLounge seat doesn’t recline the conventional way. It uses a fixed-shell design with adjustable cushions, letting you shift position naturally through the flight instead of mechanically reclining a seatback.
It includes a full-flat sleeping position, a spacious personal seating area with direct aisle access for every passenger, a large entertainment screen, multiple storage compartments, and USB and power outlets. It’s available fleet-wide on Finnair’s long-haul Airbus A350 and A330 aircraft.
On the A350 specifically, Business Class is arranged in a 1-2-1 layout across either a single 30-seat cabin or a 43-seat configuration split between a main cabin and a smaller rear cabin, depending on which version of the aircraft you’re on.
The Four Ways to Upgrade to Finnair Business Class
1. Cash Upgrade
You pay the fare difference, or a specific upgrade price Finnair offers, to move into Business Class after you’ve already bought your ticket. You can typically request this through Finnair’s website, the app, customer service, or an upgrade offer shown after purchase. It’s the most straightforward option since it doesn’t require Avios or elite status.
According to Finnair’s own upgrade terms, cash upgrades can be purchased starting 30 days before departure. Deadlines to request one vary by where you’re flying from:
- Helsinki departures: up to 3 hours before departure
- Flights from North America, Asia, Dubai, or Doha: up to 8 hours before departure
- Flights from Europe: up to 24 hours before departure
One detail worth knowing: if you buy your upgrade in advance online or through the app, you get the full set of benefits, including lounge access and priority services. If you upgrade at the airport instead, those extras typically aren’t included.
2. Avios Upgrade
Finnair Plus members can use Avios instead of cash. Availability depends on your fare type, route, and how much upgrade inventory Finnair has released for that flight. You can usually request this through your Finnair Plus account online or via the app, and customer service can help too, though phone-assisted requests may involve an extra Avios deduction.
Per Finnair’s official terms, members can join the waitlist for an upgrade as early as 360 days before departure, and confirmed upgrades are typically settled by 48 hours before the flight. If a waitlisted upgrade doesn’t clear in time, your Avios or Upgrade Benefits are refunded, though the expiration date on Upgrade Benefits doesn’t reset.
This tends to make more sense if you already collect Avios regularly, you’re on a long-haul route where the AirLounge seat makes a real difference, or the cash upgrade price is high relative to your original fare.
3. Finnair Plus Upgrade Benefits
Elite Finnair Plus members may receive Upgrade Benefits as a perk of their membership tier, redeemable for eligible upgrades instead of cash or Avios. You can view and redeem these after logging into your account when an eligible upgrade is available, subject to their expiration date and program rules.
4. Airport Upgrade
If Business Class seats are still unsold on the day of departure, Finnair may offer an upgrade at check-in, the service desk, or the gate. This works well if you’re deciding last-minute, but it’s never guaranteed, since it depends entirely on what’s left unsold. As noted above, airport upgrades generally skip the lounge access and priority services that come with an advance upgrade.
What Actually Affects the Price
There’s no single published upgrade fee. What you’re quoted depends on your departure and destination, the season, your original fare, remaining Business Class inventory, demand for that specific flight, how close you are to departure, and which upgrade method you’re using. Two passengers on the same flight can legitimately see different upgrade offers based on their own booking details.
Instead of comparing price alone, it’s worth weighing the full offer, since a cash upgrade bought early typically includes more than an equivalent airport upgrade for a similar price.
Can You Upgrade from Premium Economy to Business Class?
Yes. Eligible Premium Economy bookings can be upgraded to Business Class through the same online upgrade service and app, subject to availability and fare conditions. This tends to be worth considering on longer routes, where the flat-bed seat and added privacy make a bigger difference than they would on a short flight.
A Few Things People Get Wrong
- Assuming every empty Business seat is available. Airlines manage upgrade inventory separately from seats for sale, so an empty-looking cabin doesn’t guarantee upgrade availability.
- Waiting until the airport. If a confirmed Business seat matters to you, waiting until departure day narrows your options, since airport upgrades depend entirely on what’s left unsold.
- Assuming every ticket qualifies. Not every fare supports every upgrade method. Check your specific booking before planning around cash, Avios, or Upgrade Benefits.
- Comparing only the price. An upgrade includes more than a bigger seat. Lounge access, priority services, and baggage allowance can vary by offer even at a similar price point.
Frequently Asked Questions (FAQs)
Can I upgrade my Finnair flight after booking?
Yes. Eligible passengers can request a Business Class or Premium Economy upgrade after booking, through the website, app, or other upgrade channels, subject to availability.
Does every Finnair ticket qualify for an upgrade?
No. Eligibility depends on your fare type, ticket conditions, route, and available upgrade inventory.
Can I use Avios to upgrade my flight?
Yes, if you’re a Finnair Plus member and upgrade inventory is available on your flight. Note that Avios upgrades aren’t available on award tickets or Money+Avios bookings.
Does upgrading change my original ticket’s rules?
Not automatically. An upgraded cabin doesn’t change the fare rules attached to your original ticket, so it’s worth reviewing those separately.
Is Business Class available on every Finnair flight?
No. It depends on the aircraft and route, particularly for long-haul service.
Conclusion
A Finnair Business Class upgrade comes down to matching the method to your situation: cash for a straightforward, guaranteed booking, Avios if you’re already collecting them, Upgrade Benefits if you have elite status, or an airport upgrade if you’re comfortable waiting and seeing what’s left.
