This discussion was very interesting and I think the larger question is if there
is a way to avoid such situation if you as a passenger knows that you are right
and being denied boarding ?
- Could AA get a signed waiver from passenger removing AA from liability if
the destination country or transiting country denied admission ?
- Could AA collect deposit (via CC) from the passenger just in case his/her return
needs to be arranged if they are denied admission ? Allow them to board on
their current ticket but has the requisite deposit to bring them back.
Unfortunately training someone to understand complex visa / admission
requirements is impossible and with proper safeguards in place AA could
avoid rare situations like these....
