I just flew on the 737-800 with the cool interior upgrades.
Although I am not a frequent flyer, the next time I do fly I will fly on the 800 class again. It is truly a fine flying experience!
This was the worst cross country plane I've ever flown. The configuration is idiotic, with bathroom doors that swing out and block the aisle. Only 2 lavatories for all of economy class so people get backed up. The seats are ridiculous as far as legroom is concerned. And no pocket to store anything which leaves you with stuff on your lap or having to go into contortions to retrieve stuff from under the seat. I absolutely hated this plane! Dumb design with only thought being how many seats they could cram in.
