Up 777?
"El Al will use Boeing 737-800s for Up. Each plane will have two classes: Tourist Plus with 36 seats and 34 inches between seats, food, beverages, a blanket and pillow; and Tourist with 144 seats and 30 inches between seats, food and beverages for extra payment, and a blanket for payment."
Suppose Luton might see new 737-900ER soon.
