I have originated all of my mileage/segment runs out of EFD. Make sure to arrive at EFD about 30 before flight and you should be ok. They are very fast over there and are (most of the time) very friendly. There is at the most about a 35 minute turn around between flights so make sure that you allocate enoughg time to complete the trip. The bonuses do kick-in for each segment going in and out of EFD.
Happy Flying and Merry Christmas to all!!
