Thanks. Does anyone know if when I check in (online or in person) for my outgoing flight with BA from YVR will that in fact be checking me in for next 2 connection outgoing flights as well or only checking in for first BA flight? Do I need to check in with Iberia as well? I am confused as for some iberia flights it says I can only confirm seat selection upon check in. Does that mean when I check in in YVR or do I have to also check in 24 hrs prior on the iberia website for following connections? If my first flight gets delayed but it shows on Iberia I already checked in what happens to rebooking ? Confused.
