I flew Thai Lion Air SL370 from Bangkok Don Mueang to Macau in economy on a Boeing 737-800, seat 19F, on 29 January 2026. The flight left on time and landed a little early.
At 157 cm the seat was OK for me, but it felt small and a little close to the person next to me. Not bad, though. I didn't try the recline.
The crew were smiling and helpful. They pointed out where there was free space in the overhead bins, and told me I could use any free space, not only the bin above my own seat.
There are no seatback screens, and I didn't use the Wi-Fi or a power socket. The flight was a little over 3 hours, so I didn't order any food.
Overall a smooth, on-time flight, and I'd happily fly Thai Lion Air again.
