Boarding Passes UA and (LH) Partner
Flying UA on US domestic to gateway then on LH in J to FRA. All on one PNR UA award ticket. Question: Since the LH is international can I check in online with UA for the entire trip and print out all the boarding passes? Or do I have to go to UA and LH websites and do this separately? Or do I have to do this in person at the airport for the UA flight and show UA my passport? Or do I have to wait until I get to the US gateway and personally check-in with LH? I want the LH boarding pass in order to access the lounge - have a 5 hour layover and LH counter doesn't open until 2.5 hours before flight. Thank you in advance.
