In verifying whether members on this forum are truely passengers or not, I have found instances of people saying they were passengers yet when looking up their IP, you can clearly see they are coming from a network associated with the Airline industry.
The domains reveal people who cannot be passengers.
Well, to be fair, individuals assciated with the airline industry do take vacations as well and may have been a passenger on that particular flight. Personally, I don't feel that this association alone should be a reason to dismiss a contribution to the discussion.
