Booking Award DFW SYD
I've been looking at Aaward flights from DFW to SYD in Feb or March. When I first started looking, there was lots of dates open, but no business/first available. A week later, I checked again, and while less dates were available, several business flights opened up.
I'm sure this has been answered somewhere, but I couldn't find it, so my question is, if I go ahead and ticket my flights on the date that I need in economy, and then a business flight opens up, can I change my award flight to the business, or am I stuck with the original economy ticket?
Oh, and has anyone booked an award flight in Premium Economy? Anyone know why that isn't an option?
