Debbie - does it also then show all the travel companions? We had to use two bookings as the first was with the companion certificate. However, they were both paid for with my credit card. However, of course only my skymiles number is on my name. My daughter & her b.f. don't have numbers.
I am just going by what she told me today when I booked, however, maybe it is because we had to do two reservations that were then linked?
