I guess mainly a matter of personal preference. I always choose aisle seats just because it bothers me to be blocked in by somebody else. In a domestic flight though, it canget annoying when theother pax need to get by you for lavs/etc...

I was reading your previous posts and here is what I can add. I flew MH in Dec 2005 from LAX-KUL-KHI-KUL-LAX. The outbound lax-kul flight I was in a 747 upper deck in the very front seat, I forget the exact numbers. This 747 was a "new" one in the sense that it had the new IFE system and the coolelectronic seats. I was in aisle and sister was in window. The KUL-KHI/KHI-KUL segments were on a very old Airbus? in business class (I think). Nothing special to say about those, they were relatively short flights and I had plenty to keep me occupied. I don't believe that they had personal IFE systems

However, on the inbound KUL-LAX, we were in a "old" 747 with the crappy seats (all manual controlled- no buttons and such) and they were not the bucket seats. Also in upper deck, but this time we were in exit row. The overhead space on this 747 was MINISCULE. Practically none of the pax in the upper deck could keep their bags in the overhead bins, they all had to be handed off to the FA to keep in the storage closet b/c of size. However, the plane did have the new style IFE systems that the LAX-KUL plane had. I liked the first 747 MUCH better than this second one.
