I have 2 codeshare flights booked through United, one with Lufthansa (FRA-KRK) and one with Brussels Airlines (TLS-BRU). Last time I flew on Lufthansa with a codeshare with United, I couldn't get a seat assignment when I checked in for my flight with United online or at the airport. I had to wait until my connecting airport (can't remember if we could get it in ORD or had to wait until FRA). I couldn't get the boarding passes either.
However, when I checked my reservation on United's website, it conveniently includes the PNR for Lufthansa and Brussels Airlines. Can I check in again with those websites after I check in with United and move my seat? Or access my reservation within 23-24 hrs and move the seat before I check in with United?
These are fairly short flights and I'm traveling alone, so it's not a huge deal where I sit, but my daughter and I were split up on the previous flight, so I just wondered if this would work. Besides, I'd rather not have a middle seat if I can avoid it, even on a short flight.
While I'm at it, when I do bag drop/print boarding passes at TLS, would that be with Brussels Airlines? I think it's with the operating carrier, but I can't remember for sure. Also, will I be able to print all my boarding passes at TLS, or will I need to wait for BRU for the United ones?
Thanks for any information.
