The whole experience as amateur, from the flight attendants to the flight itself. The worst landing I have ever experienced in good weather, making the majority of the cabin doubt whether we were going to make it. Filthy uniforms and dirty old planes. I will never fly again and I am a seasoned flyer, who doesn't scare easily.
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.
