Doing some reading on
FlyerTalk someone has posted the official QR policy for this situation:
https://www.qatarairways.com/tradep.../Passenger-Guidelines-Security-Situation.html
That includes re-routing on select airlines with whom QR has interline agreements… it includes Cathay, BA, Finnair, JAL.
The guidance doesn’t seem to cover EU/UK261, which would override that commercial policy and allow rebooking on any carrier to get back to Australia (some of the carrier mentioned may not have seats left at short notice)
That policy was only updated 5 March, so may take some time to filter through, But it also appears to cover further flights, not just those cancelled and subject to EU/UK261.
That being said… there are lots of reports of inconsistencies, and QR customer service not being as forthcoming as they should be. Or claiming that award seats aren’t eligible for rebooking.
I’d be putting that down to a mismatch in knowledge between local laws and policy (contract of carriage) vs consumer law rights (UK/EU261)
Other airlines don’t seem to be having the same issues.
