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.
Look for promotions: Most airlines have special offers almost all the time. These offers are usually valid only for specific destinations and for specific dates (or days of week). If you are flexible on dates, check "what is on sale now", to get the best price! If there is no discount on your desired route and if your dates are flexible, you can wait for 2 to 4 weeks for a promotion on that particular route.
