DD2 is travelling to Hawaii from LHR via Frankfurt and Seattle (and back again) but we're very confused by the whole check in process. Travelling on one booking but with three different airlines (Lufthansa, Condor and Alaska). Does she need to complete three separate check ins or can she do it all (or some) through the Condor app as that's who it's booked with.
Has anyone done this who can advise ?
Thanks
