Out of curiosity, why is there both P4 and F4 if there are only 4 seats if FC? Doesn't the letter designation define seat inventory in each fare category ("buckets")?
Yes but F is a subset of P. So there are 4 seats that NW is willining to sell at either full fare or disconted First class prices. Congrats on the UG. Said another way, F is the "Bucket" and P is a part of that bucket.
