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
