This NYC-area flight originated at Steward Airport. For anyone living north of NYC or in upstate NY, this airport is a very convenient alternative to the NYC airports. It is a small and outdated, yet very manageable and accessible airport. Flying out of Stewart, Norwegian is a very convenient and economical choice for flying into Shannon (and other destinations in Western Europe). To Shannon they fly a fleet of brand new, 737 MAX aircraft which are clean and adequately comfortable. The convenience of Stewart, the availability of low fares, and the new airplanes were the positives of this Norwegian flight.
There were also some aspects of Norwegian that were negative, as well as some policies that potential customers simply ought to know about. Absolute negatives were a lack of legroom in standard economy and a lack of WiFi on the plane-be sure to bring your own entertainment, whatever that might be. Beyond those, be aware that the lowest prices advertised do NOT include prior choice of seat assignment, a checked bag, food, or drink. For an extra fee I was able to pick my seat (including the exit aisles with better legroom), check one bag, and obtain meals (sort of one-and-a-half meals on this red-eye flight, and pretty mediocre food). You can pay extra for these things as a package, or pay individually for the upgrades you want; my package cost an extra $70 each way, per person (i.e., $280 extra for two of us, for the entire trip) and paying for selected options individually can cost even more, so be careful. If I take this trip again, I am trying to figure out how I can get my luggage down to a weight that I can carry on (two carry-ons are allowed without charge, but the total weight limit is just 10 kg = 22 lbs. With Norwegian's pricing policies, if you need to check a bag you are pushed towards the options package). To illustrate how serious Norwegian is about what you are entitled to have with your fare, I asked my flight attendant for a glass of water some time after finishing the meal I had actually paid for, during a beverage service. I was told that they were now only serving drinks for an extra charge, but if I wanted a free cup of water I could wait until the service was over, go to the front of the cabin, and request it from an attendant at that time. Lesson here again is, if you want the lowest fare, be sure to bring your own food and don't forget to buy your own water after going through security.
