A slight deviation of the newbie's question around middle name matching that pops up so often: I have a name with First/Middle/Last - on a US passport it is listed as Given Name: First & Middle and Last Name: Last. The field for passport data in my booking asks what my First name is. Not my given name (first & middle) and not first name(s). I realize this may be fairly obvious but just to make sure there aren't problems with passport verification - should I enter just my First name in the first name field (not First & Middle aka Given?).

The reason I ask is because when asking for passport information in the FlyingBlue account pages, it asks for First Name(s) aka Given name. Unfortunately FlyingBlue won't seem to import that data into my booking so it's throwing me off that the passport data in My Bookings asks for just first while the passport data in My Account asks for given. And if it matters at all, the passenger data (not passport data) was booked under First Middle Last.
