As an example
JFK-SFO
Checkout UA 303
6am departure
April 26 (just as an example)
(NOTE I AM LOGGED IN HERE AS 1K)
If you begin a dummy booking when logged in go to "view seats"
No exit rows will appear
If you proceed to select the flight ----> select traveler----then go to "select seats" you'll see rows 5 and 9 do have seats...
Am I missing something?
