Heathrow Airport question

[H2Otstr]

We are flying BA tomorrow from BWI to Heathrow to Vienna, Austria. We arrive at Heathrow in Terminal 4 and leave from Terminal 4. Will we be required to go through security there?

 

Thanks.

Yes.

 

If you are arriving in Business Class/Club World then you can use the Fast Track security line. Just walk round the line (it is pretty clearly marked) to the front and have your boarding pass stub ready.
