Once you arrive at Suvarnabhumi Airport, the first thing to know is that you’ll need to head up to the 4th floor for all departures. Whether you’re flying domestically or internationally, it’s all on the same level. With 10 entrance doors lined up along the terminal, each leading to different check-in counters from row A to row W, it’s easy to see why so many travelers get a little confused about which door to head for.

To keep it simple:

• Gates 1-4 are on the far left, near the A-G counters.
• Gates 5-7 are in the middle, near the H-P counters.
• Gates 8-10 are on the far right, near the Q-W counters.

Before you set off, take a moment to check which row your airline uses for check-in. You may refer to the table below before heading to the airport. Aim to park or get dropped off by taxi at the gate closest to that counter. It saves you time and effort by dragging your heavy luggage across the terminal and getting worn out before you even board.

3 Steps to Find your Check-in Counter at Suvarnabhumi Airport

Step 1: Check your flight ticket or booking confirmation for the details.

The very first thing you need to do before heading out the door is to double-check your flight tickets or booking confirmation emails. They contain some super important info, like

• Flight number, such as TG123 or AK456
• Check your departure time to see when your flight takes off.
• For check-in counters, some airlines will let you know exactly where to go, such as Row D or Counter C15-C20.

Don't panic if your ticket doesn't show the check-in counter! Just keep your flight number handy, and you can easily check the information screens once you arrive at the airport.

Step 2: Look for the flight information display

As you step onto the 4th floor, try looking up! You’ll see several large screens displaying all the upcoming flights, complete with all the essential details—just like this.

• Flight number
• Where to next?
• What time does our flight take off?
• The check-in line (this is exactly what we need!)
• Check if your flight is on time or delayed

Look for your flight number on the screen to see which row your check-in counter is in, such as "Row D" or "Row K." Since check-in rows can sometimes change on the day of your flight, I recommend checking the screen every time to be sure you're headed in the right direction and won't miss your flight!

Step 3: Make your way to the correct check-in counter and boarding gate.

Once you know your counter row, all that’s left is to look for the large letter signs hanging above each row. They’re labeled A, B, C, D, and so on, all the way to W. The signs are huge and clearly visible, so just follow them until you find your row.

If you’re ever feeling unsure or lost, don’t be shy about asking the staff! There are team members stationed all around, or you can always head over to the Information Desk. They’re super helpful and so friendly, too.

Essential Tips

• This is the usual spot for the counter, but keep in mind that it may change from time to time!
• During peak travel seasons (like New Year's or Songkran), some airlines might open extra check-in counters in other rows.
• Major airlines like Thai Airways have multiple rows of check-in counters, organized by whether you're flying domestically or internationally, as well as by your seat class (Economy, Business, or First Class).
• I recommend checking the flight information screens at the airport every time before heading to the counter, just to be 100% sure.
