Scoured the thread and am pretty sure I have an idea but wanted to double-check with the experienced travelers as this will be my 1st International Flight:
Traveling PIT -> PHL -> SXM in June. Land in Philly at 8:43AM at what I'm assuming will be Terminal C. Depart for SXM at 9:35AM at what I'm assuming will be A-West. 52 minutes. I have gathered that it takes roughly 10-15 minutes to walk from C to A-West. Thoughts on if I'll be ok? Is that tight? Do International flights close gates earlier than domestic? There is at least one later PHL > SXM flight for a worst-case scenario..
Thanks for the help!
