I really doubt any Airline Pilot would be meeting women on that site. Saying he is a Pilot is trying to hook someone by thinking he is important. He has low self esteem in my opinion.
I would do a google search on him. First try to get as much info as you can. Age date of birth where he is from. What airline he is flying for. His background as a pilot where he trained etc... He's lying im sure. I have had so many funny stories told to me... None of which were true. The men on that site are all losers and not very smart. If hes lying you can catch it in his stories. Make him show you pictures in the cockpit in several different photos too. Send you a photo of his license with his name and photo showing. If he refuses any of these requests hes hiding something.
