I’m flying from JFK to HKG in economy on a ticket booked with AA miles. I don’t have the option to select a seat on either AA or CX’s website. I called CX and they said I’ll be able to select my seat when checking in. I know that Cathay members can check in 48 hours ahead, but does this also mean I can choose my seat at this time or is this restricted to 24 hours? It’s a really long flight and I’m hoping to get an aisle seat so I don’t lose my mind
