I have a J ticket on KA from PVG-HKG-BLR on the 18:20 flight (eTicket issued on AA stock).

Is KA flexible about allowing a passenger to switch to an earlier flight, provided they arrive before the 40 minute check-in time and there is space available? I'm arriving on AA 289 at 15:05 and would like to try for the 17:20 or - if the stars align - the 16:20 flight.

This type of change is usually a is a problem on European airlines and I'm interested to know how flexible KA is in these scenarios. Is this something that the First Class (OW Emerald Here) check-in agent can handle, or will I be sent to a separate ticket counter/office
