This airline used to be a great low-cost airlines. But like everyone else, it's gotten average.
1. They used to give out snacks and drinks... now it's just a tiny little bottle of water.
2. Frequent fliers used to get free "normal weight" check-ins. Now.. 5kg. I mean... 5kg? what is this for? For cases where the passenger doesn't want to carry their carry-on??
3. Pilots used to be good... now... it seems they might be hiring new pilots. The landing is like a hop before the wheels are firmly on the ground.
4. For some reason... they don't like to announce the delay of the flight until it's 20 minutes before the flight time. I'm sure they know at least an hour before (cuz that's when the other leg of the plane left the other airport)... so why not announce it so people can find better things to do than wait at the gate to find out it's delayed.
Like I said... it's just average like every other low-cost airlines. So... you might as well go with airlines like Thai Smile or Bangkok Air... since those prices have come down a bit as well.
