24h in the airport
Being in holidays for two days, I had last month bought my tickets to go to Nothern Ireland with a friend. We arrived at the airport at least half an hour before the time that was written in the email we received, but when asking for the boarding pass, we were refused because it was apparently too late... I never really travelled by plane in a big airport, so I didn't know that we should have arrived at least one hour earlier to get the flight.
We managed to change the ticket for the following day (today!) but we had to wait for the 24h in the airport, without anything but my small travelling bag and my laptop...
This resulted in some useless things, but also some more useful r2 commits. This was anyway really tiresome, noisy, and boring to death, and I wish it won't happen again (for the comeback trip, for example :D)
