35 min turnaround in JER
 

For various reasons I need to go to Jersey on Friday and ideally return on the same plane. If I book this as two one ways with a 35’ turn around…is this doable?

Have a look on the BA forum discussing back to back

This all depends on whether you end up going land side. If you do then I doubt very much that you will make your return. easyJet often have all passengers ’boarded’ and lined up in the gate area waiting for the aircraft to arrive. Turnarounds can be very quick, especially if the aircraft is behind schedule, even slightly.

You do not indicate the purpose of the trip, but you are at risk of being delayed at customs on arrival and in security on the way back. You also have to walk from the arrivals terminal over to departures terminal. Whilst that is a relatively short walk, it is not insignificant on a 35 minute turnaround!
