How a post-booking upgrade works
An upgrade after booking reprices your existing ticket into a higher cabin, and the agent handles the change on the 8 focus carriers by phone. Call 1-844-595-2859 with your booking reference, and the agent checks live upgrade availability for your flight. Cash upgrades price the fare difference between cabins; mile upgrades redeem from your program balance. The agent quotes both paths before any charge, so you choose with the numbers in hand.
Cash upgrades vs mile redemptions
Cash upgrades price a fixed difference, while mile redemptions draw from your program — and the cheaper route depends on the fare and route. The agent runs the cash upgrade against the mile redemption on the same call, quoting each total separately. On the 8 focus carriers, upgrade availability varies by cabin load, and the desk checks space before promising a seat in the higher class.
When to ask about an upgrade
Ask right after booking and again within a week of departure, because upgrade space opens as the cabin load changes. Agents check availability both times at no charge, and a mid-trip upgrade reprice keeps your original ticket intact. If the flight is full, the agent can place an upgrade request or check the mixed-cabin option on the mixed-cabin flight booking by phone page.
Upgrades with miles you already hold
Mile upgrades work across the 8 loyalty programs — Avios, ANA Mileage Club, JAL Mileage Bank, Flying Club, SKYPASS, Infinity MileageLands and Asiana Club. The agent checks your program balance, prices the redemption in miles plus taxes, and confirms the upgrade on the call. Related award travel lives on the award flight booking by phone page.
Common questions
Answers to what callers usually ask before dialing.
Can I upgrade a flight after I book it?
Yes. Agents upgrade existing tickets on the 8 focus carriers by cash or miles, checking live upgrade availability before pricing the difference.
Is a cash upgrade or a mile upgrade cheaper?
It depends on the route and fare; the agent quotes both the cash upgrade and the mile redemption on the same call — 2 paths, 1 flight — and you pick the cheaper one.
When should I ask about an upgrade?
Right after booking and again near departure — agents check upgrade space at both points, 2 looks per ticket, since availability changes as the flight fills.
