I've been hearing about longer lines at the Skytrain, so I was thinking about buying a pass for my next trip. Here is what I found about pricing:
Single Journey Pass: 16-44 Baht
Standard Rabbit Card / Stored Value Cards These are available for 100 baht plus 50 baht refundable deposit. The Standard Rabbit Cards are valid for 5 years and can be filled with a minimum of 100 baht and up to 4,000 baht.
One-day Pass Unlimited travel within the duration of a single day for 120 baht.
30-Day Pass for Adults -
For 15 trips (use within 30 days), 25 baht per trip unlimited distance, it costs 375 baht. -
For 25 trips (use within 30 days), 23 baht per trip unlimited distance, it costs 575 baht. -
For 40 trips (use within 30 days), 21 baht per trip unlimited distance, it costs 840 baht. -
For 50 trips (use within 30 days), 20 baht per trip unlimited distance, it costs 1,000 baht.
For me, I'm torn between buying the rechargeable Rabbit Card or one of the 30 day passes. Most of my trips are shorter, so I rarely pay the max 44 baht.
