I'll be flying VIE-LHR-IAD on OS/UA.
I have a 2 hour layover in LHR. Will I need to go through immigration upon landing in LHR from Vienna? Or can I stay airside to connect to my UA flight?
Thanks folks!!
Usually you will not have to clear immigration/customs at LHR in such circumstances. The glaring exception is if the travel record/APIS/passport results in being flagged and they want to grab a passenger.
Airside transits of your sort at LHR involve re-clearing what can be a security screening zoo at LHR. Two hours at LHR is plenty now and it is plenty then.
