I've traveled with Easyjet out of luton on several occasions and have generally been treated well except on the last flight I made.
I enquired with the member of staff on the desk in the departure lounge as to the reason for the delay and how long it was likely to be and was to that they didn't know and I should sit down and shut up!
I appreciate she may have been having a bad day but I wasn't impolite at all in the way I asked!
I guess at the end of the day it just depends on the individual you speak to.
