Great to hear. Typically the 330s and 767s would hit the Caribbean in the fall and winter, with regular turns to STT, SXM, CUN, SJU, and PUJ from both PHL and CLT, with some cities (like SJU) seeing as many as 3 widebodies per day, with lots of 752s thrown in the mix, as well. With the mass retirement of the LAA 763s in Q3 and Q4, I'm not sure what the combined widebody fleet slack looks like in the off season this year, but transcon routes seem like a great use of these birds and their premium seating configs.
LUS used to regularly run the 762s from PHL, CLT, and even PIT mainly to LAX, but at times to SFO as well until around 2003. Post HP merger, PHL-PHX used to see 332/333 turns, with a 762 also used on CLT-PHX.
