What name did you use for GE? I am hoping your full middle name as it will match your DL and is really what should be on your passport and flight reservations. And yes, I would get your passport changed to reflect your full middle name. Depending on how long is left until renewal, and the fact that you don't use it to fly, I would do it at renewal if it is close. If you have a few years to go, can it be changed easily?
