Hey, does anyone have experience going between lhr terminal 5 & 3 just to use the admirals club in terminal 3? I'm flying LAX-LHR-VCE and both the incoming flight to lhr and outbound to vce are from terminal 5. I've read on forums that you'll need a terminal 3 boarding pass to get to the terminal. Others said they would let you in regardless which terminal you're actually flying out of. I'd appreciate if someone can verify.
