Unfortunately the only awards tickets available are the older products even though there is the new 777-300ER making the same exact route out of my departure airport the same day. I called and they are unable to put me on one of those flights. I also don't see the ability to upgrade to the 747 first class even though there is availability. I chose windows seat top deck of the 747-8 however I'm not sure if I should switch it to the A350 or keep the 747 or switch it to an aisle seat main deck. Anyone have experience on these and which is a better experience?
