I will be making a one way reservation using my Companion Voucher to insure my outbound flight works for us joining a tour date.
Once available I will book the return using same CV.
I noticed that First Class seats seem to be available a week or so later (if at all) after the first availability for Business Class seats.
My question is: should I book Business Class as soon as available and can I then change to First Class IF they become available at a later date?
Thank you in advance to anyone who responds with information
