Hello all, collective wisdom needed if possible please.

QF2 went tech at Dubai yesterday resulting in a 24 hour delay and overnight stay.

Currently in DXB lounge waiting for today's service which I've been moved onto.

What level of compensation can I expect from Qantas for this? Missing Xmas Eve arrival is obviously an emotive issue for all the passengers involved (and crew of course!). Does the time of year make any difference to how Qantas may respond?

Also, as I boarded the flight in LHR but the issue only arose when departing DXB, is compensation still due under the EU scheme?
