I'm with the Goat on this one.
If a bunch of flagship flights are being cancelled without anyone giving a tom tit, what is a letter going to do?
Maybe this just goes to show the arrogance of the C&T clowns who think with one letter they can influence a change that 20 years of on/off CC, and union negotiations have never achieved.
Sadly a mere acknowledgement from AT is all the letter warrants.
