Has anybody tried to break apart a reservation in order to apply MTM certs? I booked my family of 5 on a mint route but we are currently all seated in EMS seats. I have 4 mtm certs, and the upgrade cost right now is 2 per upgrade. Could I split my reservation without having to cancel and rebook? Split off 2 of us, use MTM to upgrade, and then have the other 3 stay as-is? I don't want to cancel and rebook all since the prices have increased alot since my initial booking.
