hi
me and my father flew to germany, we wanted to return sooner and called air berlin. they said that it will cost 500 euros for each person to change it. and also said it will be 350 each if we wait more days in germany,
i tried to explain them that i didint felt good mentally and that it is not fair that physically disabled people will be taken much more into considiration but mental problems not,
we paid the aprox 700 euros and waited,
the whole ticket is about 950$ each,,
also it was very hard to reach them by phone and we needed to go 2 times to the airport for the tickets probing
and my luggage didn't came after landing and i waited for the next flight for it to arrive
consider a company that will considerate in you in case of problems
