I'm a big fan of Amadeus' checkmytrip.com and it's gotten me out of a few pickles in the past (where I've found out about changes but wasn't informed by the airlines).
Alas, by booking through Expedia I've been given a useless Worldspan number as they don't use Amadeus.

I've gone to mytripandmore.com, typed in the PNR and every permutation of my surname imaginable (and had my surname and PNR confirmed by Expedia) but there's no joy. (I've also tried the SAS code on their website and again yielded nothing, but that's another story).

Does the mytripandmore.com website actually work for anybody? Is there anything else I should be doing? Expedia are being completely unhelpful.

*********
and on a related but slightly different matter: I wrote this to Expedia:
the booking details stated quite clearly that I will be provided with breakfast between LHR & CPH and with a cold meal between CPH & LHR. Could you confirm this please.
and got this reply:
I can see that meals are included in your flights, but if you have any problems over meals on your trip please contact us upon your return.
Any advice on this? As I'm on V class I doubt SAS will actually honour my booking conditions - should I spend up to 5Euros each way and then claim a refund from Expedia?
