Flew in Fin 950 tonight, very old J SQ seats,, the pilot made announcements about wifi and text being available even though it isn't. Headphones in J are old 3 plug types and confused a lot of people including FAs who couldn't find jacks, even older type in center armrest area, actual ones are by headrest in center. Several seats were non functional for recline including mine..mechanics came on to fix another so it was upright for takeoff. Entertainment system was marginal with only a few very old movies. No safety videos FAs had to do demo. No front lavs so people in J kept being sent back to mid cabin lavs. The FAs were doing a great job in a difficult situation as they were unfamiliar with the aircraft too and it was a unexpected substitution. I was told at checkin I would be getting a pod so took this flight instead of an earlier one.
I would recommend avoiding these aircraft if possible .
