Every one booked on Qatar Airways to get to South Africa needs to check their itinerary. Qatar had rebooked us on a flight from Doha to Capetown 2 days later than what was on our original itinerary and did not notify us. Our flights from Dallas to Doha were the same, so they were expecting us to spend 2 days in Doha--really??
Fortunately, Ngaire caught this, and I telephoned AA who I had booked the flights through and got everything settled to my satisfaction. We actually now arrive in Capetown a little earlier which is fine with me.
