Hi all, just made several bookings through BA for flights on CX. One for a flight from PEK-HKG, another for a flight from HKG-JFK and a third from HKG-YYZ. I made the reservations online and no middle name was requested, so I just left it as first and last. When I called BA, they told me they would need to completely reissue all the tickets to add in the middle names. Will I have any problems with immigration if I leave it as is or should I add in the middle names? Thanks for the input!
