How to get a flight upgrade
I have tried on many occasions to get a free upgrade when checking in at the airport - and have never succeeded. I was wondering if anyone has actually managed to get upgraded just by asking the airline check-in person. What did you do to maximise your chances of success?
I am beginning to think it is just a myth and in practice free upgrades are very rarely given. I mean, why would an airline give away something with such a high value attached to it?
Anyway, with a long flight coming up I would love to get some ideas on how to avoid cattle class...!
