We have booked our airlines reservation to Disney however, no one and I mean no one can tell me if the armrest between the seats in the row we choose come up and where the tray tables are????we have book two extra seats for the two males in our party due to size and it is very important to make sure the armrest come up....we like the row we chose because there is an exit row in front and that will give them extra leg room.....if anyone knows any Delta airline personnel if perhaps we could exchange info so that perhaps they can help...any help would be appreciated.............
