Just checked the booking levels for NW970 for next Monday, Sept. 8.
Currently showing P7 F6 Y9 and all 9's for the rest of the buckets.
Currently booked at 9/16 in FC, but the good news is that they have added back 5 seats today in the R bucket, so 5 lucky travelers will be upgraded overnight when EUA runs.
Hopefully you are one of them!
