I have tried some low cost airlines in Europe and Asia. But I have never found some that I really like. Yes the price is good if you don’t have luggage, don’t want something to eat or drink, accept long walks at the airport and don’t see lounges as a natural part of the journey.
How ever I do like to check in my luggage, I do at least want something to drink and I think that a lounge make my trip so much better. So I avoid low cost airlines if I can. It gives me more life quality to fly a regular airline.
