How to Get a Discount When you Park Your Car at Krung Thep Aphiwat
If you park your car at Krung Thep Aphiwat and use the long distance train, Red Line train or Blue Line train, you can use your ticket or train card to get a discount. Just go to the information counter by Gate 1, 4 or 10. The regular price ranges from 30 baht to 210 baht for 1-24 hours of parking. The first 30 minutes is free. The reduced price is from 15 baht to 150 baht for 1-24 hour parking.
The other day, I did a two-night train trip and I was away for 38 hours and 55 minutes. The full parking fee was 380 baht. However, after I showed my train ticket at the information counter and got my discount, I only paid 270 baht.
I paid using the machine at the new the food court at Gate 4. This is also near one of the information counters. If you pay here, you will get an additional 30 minutes in order to leave. Alternatively, you can pay at the exit as you drive out.
