you arent looking at the Intl PMCO 752 thats why on seat guru

also any UA flight that is 4 #s and not 3 = a PMCO plane and all of PMCOs 752s had the bed seats

eg today flight 1130 @ 1:15pm is a 757 but has the beds, while flight # 806 at 10:13am (being a 3 digit flight #) is an old PMUA 757 with the domestic F seating. Just be careful that at times they will throw a 753 into the mix and no beds on those even thou its a 4 digit flight # and a PMCO plane

Also make sure to see if its a 757 , all of PMCOs planes gets a 4 digit to it and many are 737s

Of cause you can fly out of JFK where its either a bed seat or a very nice biz seat of the old PMUA ps planes

At times when things hit the fan they will sub in any plane so no 100% guarantee it will be a bed seat
