I apprecaite any help.

Ive got a MR on sat. PHX-PVD-PHX, connection in DTW. been upgraded the DTW-PVD-DTW flights (in typical NW style- about two days before the flight ), but not the PHX-DTW-PHX legs.

those are the long ones, with meals and what not. there are still seats up front but not R class.

what's better? check-in at the 24 hour mark and get on list, or possibly snag a newly released seat, or wait to check in and let the system sweap again in hopes of the getting the EUA. i know on CO, this concept is highly contested. not sure about NW. this would be my first NW flights without early EUA's in nearly 5 years.

Thanks.
