I’ll be flying SEA-ATL-Madrid on Delta and changing to Air Europa for the last leg to Mallorca. All on 1 ticket from Delta (air europa is a codeshare).
I was planning to use carry-on only, thinking it would expedite my early morning journey thru SeaTac by not having to go to the checkin desk. HOWEVER… it sounds like even though I should be able to “check in” online I may have to go to the Delta checkin desk anyway. Maybe they want eyes on my passport? Maybe because it has a codeshare?
Does anyone have recent experience with a multi-leg trip like this? Will I be able to get my boarding passes online at home? Will using only a carryon allow me to go straight to TSA and the boarding gate, without stopping at the checkin desk first?
Thanks!
