Computed as the departure date minus the published window, from Oct 18, 2026. It is the earliest the published rule would open a date; actual release can run earlier or later, and a date shown as open now may have sold its seats. AwardTool's observations in the last 30 days are below.
Mileage Bank awards vs the airline that flies you
Mileage Bank is the program you book with; the award itinerary is flown by Mileage Bank's own airlines or its partners, who release seats on their own schedules. Below, the furthest open departure AwardTool observed in the last 30 days on Mileage Bank award results that showed a single airline.
| Airline (marketing carrier) | Furthest open departure observed | Single-airline results |
|---|---|---|
| Japan Airlines (JL) | Sep 13, 2027330 days out | 39 |
The airline is the marketing carrier, the one that sells the seat; another airline may operate the flight. Partner airlines often release award space later than the program's own flights.
Initial release and later availability
Many programs load an initial batch of award seats when their booking window opens, then add or remove space as departure nears. So a Mileage Bank date that shows nothing the day it opens can gain award space later, and space seen today can disappear.
Business- and first-class award space, and partner-airline space, often appear later and in smaller amounts than economy on the program's own flights.
