Hello,
[time of flight], [people flying] [was/were] booked
on flight [flight number] for [destination], flying out of
[airport name]. I thought I should let you know that during the
flight, your flight crew behaved most unprofessionally and on some
occasions were downright rude.
[description]
This kind of behavior is simply unacceptable from a professional
airline. Please take steps to see that it does not happen again. If you
wish to contact me about this matter, you can reach me at [phone
number]. Thank you for your time.
Regards,
Jim Karter
