Your flight from PHL to MCO will most probably be one of the new 737's.
If so, it will have a monitor on the seatback in front of you with lots of features, including TV, music, flight following, etc. Just bring your own earphones. There will also be a port to charge your phone if you bring your cable. If you get an older 757, there will be monitors throughout the cabin, but you'll still need your own earphones. Many flights have wi-fi for a fee ($10?). They also have drinks and usually light snacks, with food for purchase.
The flight from Burlington to PHL will probably be American Eagle, which will have few in-flight amenities. Probably just drinks.
