An average flight with minimal service as expected on U.S. domestic flights of this length. I can understand a limited beverage service, but reducing it to water only seems a bit extreme. At least there was a package of snack mix to accompany the beverage.
For this short flight I think the comfort level was fine. The ability to be able to sit by yourself in one of the single seats on the left side of the plane is a major plus.
LGA might not be the best airport in the world, but its proximity to downtown NY affords some of the best aerials for those in a window seat.
