I need to book 6 tickets which are each $98. I have several $200 credits remaining, so I'm hoping I can take advantage of them here.

I'd like to keep all the tickets on the same reservation, so I'm thinking that if I buy two $98 tickets for P1 and P2 in the party, then cancel, and two more $98 tickets for P3 and P4 and cancel, this should work? Because then I can use the travel funds for bookings in the same name for the first four and the remaining two $98 tickets for the final $200 credit. And as far as I know, travel funds and credit card can be used at the same time so it could all be one reservation in the end.

Does this make sense? Or am I missing something that would cause this plan to fail?
