What is web check-in?
Most airlines offer online check-in. This opens between a week and 24 hours before your flight, and allows you to confirm your presence on board before you even arrive at the airport. That's why we leave it to you to check in yourself. Indeed, in the current context we cannot confirm your presence for you.
During check-in, you can choose your seats, add luggage or services, and collect your boarding pass at the end.
If you have no hold luggage, and you are travelling without any special controls, travel documents or visas (e.g. in the Schengen area), this boarding pass allows you to go directly to your boarding gate without having to go through a ticket counter!
