Im guessing you fly for Eastern?
I wouldnt worry to much. I have been on the dash 8's for almost 3 years. Today was the first day EVER that I felt ill on the aircraft. Almost to the point of reaching for a little white bag myself. Yes, I was feeling dizzy and just not in top form today.
As said...this is the first time in 3 years of flying that this has happened.
See how you go over the next week or so. I am sure you will be ok.
I have only ever known one Fa that had to leave flying due to travel sickness.
Goodluck!
