It seems fewer and fewer DL flights in the JFK-SEA market are being operated with BusinessElite (recliner) seats than before. Back in late 2012/early 2013 DL delegated these aircraft to SEA (along with LAX & SFO) and provide the enchanted onboard meal service, Tumi amenity kits, Westin pillow and duvet set. Lately it seems several daily flights are operating with 75X (26 F seat) and 738 aircraft which lack even recliner style seats. DL maintains the no medallion upgrade policy in this market nonetheless. At anyways this is a deceptive practice as they have marketed it as full BusinessElite service but seem to be backpedaling lately. They should either maintain the full BE service or go back to serving it like any other domestic route and permit Medallion UGs. Also of not, DL only guarantees flat beds on JFK-LAX, not even SFO. I assume it's only a matter of time until the mods get completed and they are offered on JFK-SFO consistently. Maybe DL realized SEA doesn't produce the same premium traffic as LAX (or even SFO).
