When planning a flight, I choose only certain companies with good reputation and positive reviews. Comfort and safety are the most important criteria in choosing an airline. Of course, cheap tickets are not always an indicator of quality, especially if it is a promotion or discount. I have enough money to ensure a flight in favorable conditions. I prefer to fly business class. Regardless, I can also build a cheaper and better route to my destination. In general, I don't really like to do that. So I use the airline's services to choose the best routes and accompany me from the beginning of the flight to the end.
