You can clearly see this is an attempt to add more per-flight profit just by virtue of increasing the number of seats. Unfortunately, this means a few things for passengers: First Class features fewer seats meaning those seeking a Status upgrade are less likely to be successful. Premium Economy gets you the First Class food, but not the wine & liquor selection - and is only really worth the extra expense if you get seats A, C, H or K ... D, E, F, G are not really worth it in my opinion. The seats are more comfortable (mind you, I'm 5'6" so the overhead bin would be comfortable for me) than Economy, but the middle row still seemed crammed. Economy ... was ... just ... terrible. Even for a shorter guy like me, I was uncomfortable for the duration of the seven hour flight - my heart went out to the guy beside me who was easily over 6'.
Flying these days is often a huge hassle: You have to get to the airport early to make sure you get through security in time, and then there's the issue of the flight itself. One of the biggest issues related to your comfort and a pleasant trip is where you sit: how much legroom the seat has, how wide it is, and how much overhead bin space there is above you for your carry-on luggage. Other considerations include trying to avoid the middle seat in a group of three, getting your preference for a window or an aisle seat, and sitting close to the front of the section so you can deplane more quickly. If you pick a good seat, it makes the whole journey a lot better.
