Just got an email advert from a Big Airline (They ain't my fav airline) that says:
On some airlines you can't even choose your own seat.
Well, I can't be @rsed to go to their web page and look for the small print that has the get out clauses.The correct statement is given here.
On some airlines, you can CHOOSE your own seat and then wait to see which seat you are given on the day.
