I have two questions. The first is has anyone recently transited through London Heathrow on their way to a final destination? I cannot figure out if I have to fill out a passenger locator form if I’m just changing planes at LHR.
My second question is the layover at LHR is four hours. I have no worries about making my plane as it is a long layover, so I was wondering if the United lounge is worth it for a $59 one time pass. Any information is appreciated!
