I had to rebook a flt that was scheduled for july 2021..wanted to move it to Oct 2021.because of covid 19 we were told we could re book up to I year after original booking.thet told me they rebooked it and sent me new itinerary..I was told later that etihad airlines had canceled the flt..so i tried to rebook for another flt.they said there would be a fee of over$ 800.00 I was told originally that there would be no change fees involved if I needed to change..they just give me run around..help desk just hangs up on you
