Reviving this thread.
I have a UA-ANA ticket on the same PNR on 016 stock. CLE-ORD segment on UA, then ORD-HND-DEL on ANA. My UA flight arrives ORD at 8am and ANA flight is 5pm same day. I understand that ANA counters don't open until 3 hours before the flight time, so I am wondering if UA will through check my bags at CLE all the way to DEL and issue me boarding passes for ANA? Or do I sit around waiting for ANA to open and check in again at ORD? Thanks!
