Asking from Australia and about Malaysian Airlines specifically:
How good a case is it to seek compensation for flights if the airline failed to check documentation correctly and let us board in the first place?
My partner and I boarded a flight to a destination for which, it turned out, he was unable to gain a visa-upon-entry into (Australian travel document, Thailand).
We were subsequently put on a flight back to Australia of which we were told we were 'covered' by our return flight fees. In short, we essentially lost the return fees in full, and incurred additional costs from an airport hotel overnight due to flight connection times.
Is this something that could've been avoided if the airline had checked the validity of the travel document in the first place, so that we could have at least remained at home and claimed a refund for the return leg of the journey?
What is the best way to go about addressing this issue?
