Hi
I am hoping that someone can help with a slightly odd query!
We are looking at booking reward flights for a holiday next year but 16year old son wants to bring his girlfriend! In 12 months time I’m concerned they may not be together (they are only 16! )
I am looking at using companion vouchers and points. How am I best to book the tickets?
I was thinking that I should try put myself & husband on one booking ref and son & girlfriend on another booking ref.

If the girlfriend is no longer on the scene and doesn’t come, can I just drop her off the booking or do I need to cancel and rebook?
I might be overthinking it but any advice before I try booking would be very welcome.

If you’re using companion vouchers for reward seats, you should be able to drop her from the booking, have the voucher refunded, the taxes refunded and have your son stay in his reward seat.

Thank you very much for your help.
Always prefer to have as much information as possible before I try calling Swansea
