To use Twilight Check-in, you’ll need to check in online any time from 28 days and no later than 24 hours before your flight, via our website or app. If you’re unable to check in online during this timeframe, it means our online check-in allocation has been reached. In this case, you won’t be able to use Twilight Check-in and you’ll have to go to our check-in desks at the airport on the day of your flight instead. The best way to make sure this doesn’t happen is to check in as soon as possible after online check-in opens.
