Love this. I am rather reluctant to take photos of people in busy places so admire all who get great shots like this. Heathrow? Looks a bit hilly and sunny :-)
@kametty Well spotted. I have now corrected my error as it was Barcelona airport. My phone has a great zoom so able to get such sneaky shots with much more ease. Always feel happier catching people from the behind.
I feel the same as @kametty sometimes so it is really exciting for me to be able to catch a shot without the people knowing. You did an excellent job here with this one. You need to fix your narrative though. It still says Heathrow.
Well done!
