We were in Valencia and HAD to be in London by 5:00 the next day. Horrible weather lead to our 4:30 EasyJet flight being cancelled, but not until 9:30. EJ's plans would have gotten us to London too late. We scrambled, made our way to Madrid and caught an Iberia flight that left on time and arrived early <:
The fare for tickets purchased about 12 hours before departure was much lower than anything else available that day.
The plane was clean and comfortable enough - kind of like the budget airlines, cramped but ok for a short flight.
