As a Continental Flight Attendant, our easiet and best plane to work is the 767-200. It's so small and so big at the sametime. The AFT galley is huge and there are no lavs back there, so we never have to worry about strap hangers and LAV lines. The plane Domestically is staffed with 6/7 F/A's and there is only 174 seats on the entire jet. The pax to F/A ratio is wonderful, and there are alot of LAV's and there is that huge lav in the middle. It will be a sad day when we retire those jet's. I love the sister jet to, the 76-400, great staffing and lot's of work space.
The 757-200 is a great pleasure to work also. Since they put on the PTV's, that is about the only thing that can be a pain to work during the flight. The 757-300 *when* staffed with 6 instead of just 5 is also very easy to work. Nice plane, great lav set up, and there is plenty of room to stretch, and stand without being bothersome by the 3 lav's in the back.
I don't really care for the 737-800, except for the one with the mid-cabin lav. It's almost like working the 757-200. The other 800's have to many seat's and not enough lav's, and also have no place to stand or stretch for a few mintue's. The new 900's are ok and will be great when the get the Live TV, the old 900 aircraft set-up was really nice, but it's almost a complete thing of the past. The only 737 I really love is the 700, 12/112, great aft galley, closet space, love the drop down tv's, comfy seats for pax. The 300 is a nightmare, and is only partly better if you get one of the few with the old CRT/Sony system onboard.
I like the 777 and it's very nice to work, when it's not full. It just has to many Business/First seats for my liking. Alot there is ton 's of space and actualy crew rest area's, this plane only travel's to a handful of place's I like working to.
