We have just changed our plans to arrive at MCO in the evening of Feb 14th. We are probably leaving PHL no earlier than 8:00pm, which means we won't land until 10:30 Will DME still be running when we arrive in Orlando?
Expanding on that answer yes, since you will have DME reservations and ideally will have provided them with your flight information, they will know you're coming, about what time you're coming, AND will be monitoring flights in case of delay.
