An upgrade requires several things, depending on the kind you would like to book. The main thing is that there must be free seats in the higher class. There is also a time limit: You can book an upgrade from 360 days before your flight until 24 hours before departure. You can find all the details here.
No, the fare conditions of your original ticket still apply after the upgrade. This means the rules for changing your booking, getting a refund, and baggage do not change. You still get the same baggage allowance as your original ticket.
We offer a selection of snacks and high-quality meals that vary depending on your travel class and flight duration.
