Data Point for more confusion:
Alaskaair.com is now showing a lot of F space that matches EF.
Last night I called the partner desk/reservations, the agent was helpful and friendly but it didn't get anywhere.
as.com showed Z2 on JFK-DXB she said it wasn't showing on her system.
So I booked JFK-DXB-SEZ online in First. To get a stopover, the system calculated it as a massive layover something like "192 hour layover"
2 Passengers 200,000 miles, First Class $50.20 in taxes. I'll take it!
I really don't like my DXB-SEZ onward dates, but hope to change this once I am in Dubai?
(I think that is possible since I won't need space on the outbound leg, having already flown it, maybe I can even call it in from the plane.)
