That's unfortunate.
What do you think the flight attendant should have done?
It sounds like you would prefer the passenger to have been placed in restraints all the way to BHX? Or should the aircraft have been diverted to deplane the passenger? Should you have been upgraded for the inconvenience?
Good complaints should state
a)what happened
b)what you think should have happened, but did not
c)what you want to happen to make amends
If you answer questions b) and c) for us, we can offer you more advice.
