But the usual rebooking conditions do indicate direct routings are allowed/encouraged with QR. It may be that regardless, if you claim EC261 off option 2 they may pay it anyway, but I don't see them as being required to do this.
I would actually prefer the nonstop option, however I need to go through LHR and yet arrive around the same time frame I originally booked. So in my case, option 2 is the only one that really works. If I want to claim EC261, when is best to do so, after I have completed the trip or before departure?
