Do you have to pass through immigration when arriving at Terminal 4 and departing from Terminal 3 on TWOV?

The layover is just over 3 hours. Is this sufficient time to make a connection?

Flight is SVO-LHR-LAX on multiple carriers.

PS: In case of different carriers, how do I arrange the luggage to be transferred to the next flight without passing through immigration?


  • In LHR there are connections airside as well as land side, but whether you can use them may depend on the ticket(s) you have.

  • Could you please explain what type of tickets allow air/land transit? I have Aeroflot SVO-LHR and Virgin Atlantic LHR-LAX. Both return, both require transit at LHR.

  • To clarify, did you book two separate tickets (one with Aeroflot and one with Virgin Atlantic) or just one? Dec 16, 2017 at 22:40
  • @ZachLipton I didn't buy two separate tickets from respective airline websites. I used a travel booking site to find affordable fares and it showed multiple carrier connections through LHR, which I bought. Would it be considered as 'one ticket'?

  • @Marbles not necessarily - do you have one single booking code or ticket number, or do you have two separate booking codes or ticket numbers?

You can transfer between all the terminals at LHR without clearing immigration, so if your ticket is in a single booking or you only have hand luggage, you do not need to clear immigration

With separate bookings and checked luggage, you'll have to clear immigration to collect the luggage, which you can do on your US visa.
