I have learned a lot from Mandi and Tallg. Thanks. Thanks also to Awkhan for opening up such topic.

I have no choice choosing Qatar Airways. I'll save at least 3 hours travel time compared to other airlines. If there's only a direct flight from other airlines....

I got bumped 3 years ago. It's along story in the airport but as a compensation to my incovenience, they gave me a free 1-way ticket to any destination equal to or not exceeding the distance from Qatar to my home country.

Do an early check-in. I usually do 12 hours before.

Has anyone tried already this so called "online check in"?
