Front end here !
We participate in Fam flights, bit of a hiccough recently but they are back again. Visited ATC at Wy Aye International since I'm up here for the summer. Trying to get them up with us and they can see for themselves why we despair when other operators either slow down in front of us, or apparently don't stick to their assigned speeds.
Last year going into MAN we were following a light blue charter operator who was on an assigned 290 knots. We were on 280 and doing it, yet mysteriously catching them up at an alarming rate !.
Nowadays, if I am 30 miles behind either them or our orange cousins at say 30,000', I find myself asking if they want me to slow down because I know I will catch them up with no speed busts anywhere.
