Been wracking my brains trying to think of a company/brand I dislike and then I remembered Ryan Air.
In a remote French airport I put my bag on the scales and was told it was overweight and the extra charge was 90 euros. Can I have my bag back to take some stuff out please, says I ? No, came the reply, it's already been checked in. 😡😡😡
Can't say I've never used Ryan Air since, but avoid them if at all possible.
