I question anyone who says PHL is a good airport for connections. Taken as a whole, PHL isn't as bad as some say, but not for connections. There are MANY better airports connection-wise. Saying PHL is good because it's "one long terminal" is ludicrous. Granted, I would argue PHL is better than say ATL, but PHL is certainly not better than CLT (for example).
The article mentions that US is using 767s in Dublin. Did they go back to that? I thought it was all 757s now.
Most of last year the service to DUB was 767 but this month it has gone back to the 757.
