My husband just flew back to the UK for a weekend with US (!!) via Phili and reports that they were fine. Flights on time, comfortable, easy connection. The UK leg is very comfortable. The US leg is as you would expect any internal flight to be as it is like a bus ride here, no film, pretzels and a coke ( no meal) but all internal flights are pretty much like that. You used to get a doggie bag ( paper bag with a bun and some crisps) but most dont offer even that now, Thankfully it is only 2 and a half hours. One comment, if you have a long gap, Phili airport is a bit devoid of things to do.
