I've only got the one data point, but I had a bit of a nightmare flying experience with Wings Air, a part of the Lion Air group. I was flying from Denpasar to Labuan Bajo and Wings was one of two airlines that I could've chosen. It started out as delays with no explanation of why. They finally called it for the night, explained that it was a mechanical issue and they needed to fly in a different plane which wouldn't arrive until the next morning. The put us up in a dingy hotel in Denpasar and told us it would be a 9am flight the next morning. So I went to sleep to wake up in time. They then delivered our luggage to the hotel without telling most of us. At about 2am, I got a knock on my door from another passenger that I'd become friendly with during the delay. She'd had difficulty sleeping and had gone down to the lounge to read only to hear that the flight was now scheduled for 3am and that we'd need to leave immediately. Had she not alerted me, I'd have been one of the many people in the hotel that were left there. As it was, only my luggage was left there and it took me calling the hotel 3 days later to have them search before the airline"found" it almost a week later.
The whole thing was a shitshow and I can't recommend strongly enough choosing any other airline if you've got the choice.
