I just booked an award ticket and am having second thoughts about my BKK-ICN leg in business. I have until midnight to make changes. The flights below all leave in the same half hour. Options: OZ 742 Airbus A330-300 TG 658 777-300 TG 658 777-200 I booked the OZ, but it has angled flat seats and I am not happy about that. I can't figure out the difference in the TG flights--would either have a fully flat seat? Thanks for any help!
