Also, in your case, since the GE card normally has the name the same as the passport, be careful about your middle name on international tickets where you may be required to have the passport match the ticket.
You can change it, but you have to call in to change it, no changes can be done online.
As for the name and passport, all DL and most airline care about is that the first and last names match. If a middle name is on the passport but not BP or is on BP but not passport DL will still allow you to travel. What they won't allow is someone to travel with first/last name different then when it on the passport. If for example you get married and take your spouses last name. You however don't update your passport. You must be ticketed as the name in the passport. If you go to court and change your first name, but dont change your passport, then you must ticket under the name on the passport. A number of airlines don't even print middle names. My middle name is on my passport, but my DL reservations are all only first/last name.
