Getting seat assignments 24 hours ahead
If I'm on a *A airline like Lufthansa on UA stock, when does the 24 hour window start? If I go from HNL-SFO-FRA-JNB and the Lufthansa flight is FRA-JNB, can I get a seat assignment when I check in at HNL or do I need to wait 24 hours before the Lufthansa flight?
