For now, in PHL international is 'I' for Islands. Mostly in and outs with a handful of layovers. AUA and UVF are the most common layovers from what I've seen. Still, the majority of PHL is domestic, which includes Canada and Mexico. It is a great mix of flying though IMO. Now what happens when the XLRs get here and how that changes the flying; who knows. But it's a good thing to look forward to.
