Hi,
I got the same message for an upcoming flight I have in a few weeks: DUB-SFO-PHX connecting with United in SFO (full itinerary ticketed by Aer Lingus).
I wonder, now they are landing in T1 and United departs in T3, whether I will have to go out T1, shuttle train to T3 and go through security again (before we could just walk airside to T3 for United connections), and whether need to collect and re-check bag in SFO?
If anyone is connecting in the next couple of weeks at SFO to a United flight, I'd appreciate if you can post about your experience.
Thanks
