My parents flew with this airline, and they actually didn't mind the lack of "luxuries". Actually, my dad claims to have been able to lie across 3 seats and sleep the entire flight! No one bothered him to ask which meal he needed, since none were provided. This was Copenhagen-Boston, round trip. Besides some minor delays, there was nothing at all wrong with flying with them. Remember, if you cut costs, you can't expect things to run 100% perfectly. Hopefully there is no hit upon safety, I think federal regulations prevent that.
Fly on workdays: As many passengers prefer to fly on week-ends, week-end tickets sell first. If you don't book your trip well in advance (2-3 months beforehand) you may notice, for example, that Thursday flights are cheaper than Sunday flights. Some low cost carriers have special promotions on the flights during the week.
