Those flights were set up as pre-merger PHL reliever flights. With JFK and MIA in the mix now, IMO, they will not return. Both LIS aand BCN are PHL seasonal and they are bookable for 2015 (BCN from Mar 5, 2015 and LIS from Mar 28, 2015). If the CLT flights were planned to return, especially the air/cruise schedule dependent BCN flight, I'd think they'd already be bookable. MAYBE CLT will get a (new) seasonal MAD, but other than LHR, I don't predict much more. I'm afraid the CLT dreams of CLT-TLV, etc. are just that.
