I was stranded with 2 (albeit adult) children on 9/11, in London, during a long connection. The (in)famous British airline assumed no responsibility whatsoever. All would-be tourist services were price gouging the unfortunate who were stranded. I personally, boycotted that airline for 20 years, as a result, until i decided to let bygones be bygones. And then they pulled another zinger, and I was a full fare business class.
