Qatar Airways Codeshare Partners Are Accommodating UAE Travellers At No Additional Cost

Travellers booked on Qatar Airways flights are being accommodated by codeshare partners of the airline at no extra cost.
Anyone flying out of the UAE who is unable to travel via Doha is likely being accommodated on alternative airlines.
Passengers looking to travel can call the Qatar Airways call centre to reschedule flights.
We managed to get ours done as well, re-booked on Turkish Airlines. Took 45 minutes+ to just get through their lines though.

It comes following the fall out of Qatar with Saudi Arabia and the UAE
Which was announced yesterday. Emirates, Etihad, FlyDubai and Air Arabia all announced their flights to Qatar would cease, while airspace in the UAE and Saudi is now closed to Qatar.
