Hi, looking to book LHR-VIE-IKA next year which has a connection time of 25 minutes. We are UK passport holders, never flown Austrian before.

Can anyone advise on the transfer process itself? Do we go through security again? Or just out of one gate and head to the next? As IKA isnt EU i wasnt sure how that worked to have such a short MCT.

As the VIE-IKA leg is over 4 hours i'd want to have a large bottle of water with me for the flight, hence asking about security/liquids, as 25 minutes doesnt appear to leave us much time to pick one up in VIE.

Appreciate hearing any recent experiences. I'm not good with MCTs, I once had a 45min flying DUB-LHR-JFK and it was really stressful but mainly as we had to go through security and switch terminals.
