The XLR going to (mostly) PHL will help grow the base. We're getting 50 of those things...and even if it's just 12 daily flights (it will probably be more...the XLR will open new thin international routes that the 757 and 767 served...but will also be used to add frequency on other routes), those additional new routes means more domestic feed into that international hub. PHL's main reason for existence is that niche European flying that's not well served by JFK.
