What do you guys think of a 90 minute connection time in BOS from PHL-BOS to an Aer Lingus award ticket to Dublin? It would be on separate tickets. If my memory is right, that would be a B to E connection. I'm sure it's "legal," but it seems risky to me -- mostly the on-time reliability of the PHL-BOS flight. It seems like every time I fly that route, especially in the afternoon, there's a delay.
Physically, I'm thinking it's probably 20 minutes between gates (walking), plus 10 minutes for security. No checked luggage involved, but I'm not sure if I can get an Aer Lingus boarding pass in advance (I'm guessing I could).
A flight with a 2 1/2 connection will cost me $50 more. Money well spent?
