Your TSA precheck information (usually) has to match the exact firstname/middlename/lastname as what's printed on your ticket. Problem is - SQ doesn't have a middle name field. They only have firstname and lastname fields. For those who have their middle name registered on GE/TSApre, have you ran into problems with getting TSA pre to work while flying SQ? If so how did you fix it?

One thought is to put both your first name and middle name in the "first name" field on the SQ ticket. But will this trip up the matching, because TSA pre is now seeing an erroneous first name and (still) no middle name?
