The Route from Suvarnabhumi Airport: Airport Rail Link (ARL) to Phaya Thai Station costs ฿45, runs every 10-12 minutes, 6AM-midnight. Journey takes exactly 28 minutes including stops. At Phaya Thai, walk upstairs following BTS signs - it's the same building, elevator access throughout.

BTS Connection: Transfer to BTS Sukhumvit Line (green line) costs ฿16-44 depending on final destination. Get a Rabbit Card from machines at top of escalators - saves time with kids. Day pass ฿140 if you're doing multiple trips that day. Total maximum cost ฿89 vs official taxi ฿300-450 including airport surcharge and tolls.

Why This Works With Kids: Elevators everywhere, air-conditioned trains, no traffic stress. We travel with three kids plus strollers and this route beats sitting in Bangkok traffic for 45-90 minutes. Pro tip: ARL connects to MRT Blue Line at Makkasan if that's closer to your hotel.

When to Take Taxi Instead: After midnight when ARL stops running, or with truly massive luggage. Use official taxi queue Level 2 - never accept offers from airport touts who charge double. But 90% of the time, train wins for speed, cost, and sanity with exhausted kids.
