Booked a return package with expedia. Its Dublin > London > Kuala Lumpar > Koh Samui. I am flying Aer Lingus > Malaysia Airlines > Bangkok Air.
AL have an interline agreement with MA.
MA have a codeshare agreement with BA.
I assume I can booked all the way through as its on one ticket? On top of this, will I have to pay Aer Lingus the baggage costs for all the airlines? I assume Aer lIngus in Dublin can provide me will of my boarding passes?
