I've never booked SW with points before, so I need a little help.
Can I book my family of four on one reservation and use points from each of their accounts?
If you are using points from one account then you can book it at one time. That's if you have enough points in one account to do more than one booking. Then, you book them together, but it does give you separate confirmation codes and seemingly separate reservations. If you want to use each individual's account to reserve their own flight, then you book each one separate while logged into the appropriate account.
Or must I do each reservation separately? And if I must do them separately, is it a problem to have children on their own reservation without an adult?
