Just because you have too many pajamas doesn't mean no one else wants them. Qatar and Qantas provide pjs in business. Don't take them if you don't want them.

The amenity kit is very nice but an update every once in awhile is nice so that you have some variety instead of having multiples of the same one.

The A380 style seat would eliminate having to climb over anyone, wouldn't increase the number of passengers and would make seating consistent across the fleet.
