I have seat 12A and B on the 19-09 flight from heathorw to miami and as WTP starts at row 12 it should be an older 747 that holds the empower adapters. I am aware of the fact that the plane might change and the adapter will be useless. I have no intends to buy one as that must be a waste of money. Allthough if someone offers a cheap one i might reconsider
