We're trying to book tickets to Anaheim for a family of 5 using my husband's as well as my WestJet MasterCard. We each have quite a bit of points but also want to use one companion voucher each. Is there a way to book everything at once, or will we need to book twice.? I'm wondering if we book the first three tickets on my MasterCard using points and companion voucher then do a second transaction with my husband's MasterCard using points and companion voucher the last two digits if we might end up not being able to get tickets on the same flight if it sells out or maybe the price will go up for the second transaction. Does this make sense? Any tips?
