Then having to phone up every booking for comfort seat booking is best?
Not sure what the VA call cent(er) calls them in MNL tho.
One time when I wanted it on an a320 PER - ADL, I had to explain, and the CSA asked if it was for a music instrument, so I would say that they have an inkling of what it means when we want the extra seat, sort of.
The comfort seat booking/extra seat, also benefits the other person, so you are paying for 1.5 actually, instead of 2, as the person next to you on that 737-8/737-7/320 will also gain by not having someone next to them.
