My family and I were unfairly denied access to our flight. we arrived at the gates 20 mins before take off. Our bags are on the flight. they said they could not board us because the bus to the plane had left. we were never told we needed a bus. the british airways employee said it said so on the boarding it. it does not. the boarding pass says get to flight 20 mins before which we did. Nor were we ever paged. Our bags are now in Athens and we are not getting on a flight till 8:30pm. I am now stuck in Heathrow without my stuff trying to keep my 5 year old daughter occupied for over 6 hours. This is not right. We followed the directions, but your employees decided to deny us access anyway.
