THB1,000 is outrageously expensive. My guess is that you took the airport taxi rather than the normal public taxi.

Alright here's the situation. When you arrive at the airport, you have a few choices to get to your hotel:

1 - Hotel Transfer

If you arrange with the hotel via bookings, they could send someone to pick you up from the airport using the hotel limo. Might be free, but if it isn't, you can expect a heavy bill. Pros: No need to wait for queues

2 - Airport Taxi

When you exit the airport and about to head outside, you're most likely to be approached by well dressed men / women in blazers asking if you like a "taxi". This ain't any normal taxi, but your high class airport limo. Depending on your destination, it would cost anywhere between THB600 - THB1,000. Pros: You get to sit in real comfortable Toyota Camrys

3 - Public Taxi

The cheapest form of taxi to get to your hotel. Head downstairs to the ground floor (not the arrival floor) and head outside. The new Suvarnabhumi airport hasn't properly prepared proper booths for public taxis, so you'll see a bunch of tables by the sidewalk. Walk to anyone of them and tell them your destination. They will give you a receipt and show you to your public taxi. The journey shouldn't cost more than THB400 if you want to get to town center.

There is an extra surcharge of THB50 if you take the public taxi from the airport, in addition to the metered fare. Also, if you decide to take the tollways, you have to pay the toll fare yourself.

Pros: Cheap. Cons: You might end up sitting in a 1990 Toyota Corolla or an old junk rusted relic of Bangkok transportation antiques
Some Tips:

Most public taxi drivers will take the Bang-Na route to get to the city. It's further, which allows them to earn slightly more milleage from you. So, if you are daring enough, tell the taxi driver to take the "Motorway" route. This route is shorter distance, and more direct to the city. "Motorway" is the name the Thai's use for that particular stretch of highway, which leads you to the Rama 9 Rd, and from there you can get to the city with ease.

The Bang-Na route shares the same trunk to and from the port. With this, you will have to bear slow traffic from hundreds of container trailers. If you're unlucky, you might experience some traffic congestion, and that can be really frustrating.

For first rides only

Guys, grabcar apps in ios why got two? Which ine  an be use in thailand? Grabcar cheaper/safer than using their public taxi right?

For first rides only

well actually its the same price.

Grabcar is just regular taxi, but they join Grabcar. Standard metered and toll charges apply. Standard safety awareness like when you are in Malaysia applies. Lets just say this, most local women will not take taxi alone during the night in Bangkok, unless distant very short and motosai didnt cover that route.

Pro
-can see in the app where is your taxi
-confirm can reach where you wanna go if language is a barrier. but usually u still need to tell the driver where exactly u wanna go or where u wanna
get off. This city is too big with too many tiny soi.

Con
-taxi u request might not turn up or abscond on you. But this rarely rarely happens and only on 2-4am timing and also highly depended if the driver is lazy or not.

i used grabcar last year and it was fixed price only, so they changed the fare system already?

fix price when it was just launch in thailand perhaps. It is based on meter now, like regular taxi.

oh i see, so their app there is like uber?

Tried Uber in Bangkok, it took a long 40 minutes to get the driver reach me because of the traffic jam there. Pity the driver that the fare ended only 120baht with a 10 minutes ride back hotel.

u should have cancel the ride , if it was 40min waiting time...

Sure about it? 

As far as i know

Grabcar: Fix price, like Malaysia grabcar, price is fixed (depends on traffic, high fare when high demand) (Example: the price stated is Fare: 100baht)
Grabtaxi: Normal taxi by METER, also like Malaysia's grab taxi (Example: Estimated Fare : 100baht to 120baht)
