I am going to Bangkok on this coming August. I have my flight back to home on 3rd of Sept at 7.25am. Can anyone suggest me the best way to travel from bangkok to airport in such as early time? Thanks..

If it was me, I would ask reception of the hotel you stay in. A day before you’re due to travel tell them your flight time and they will suggest the best time to leave for the airport.

I use meter taxis and allow an extra 10 minutes for one to be hailed off the street by the bellboys.

What could a hotel reception suggest? They may have never seen a plane or been at the airport in their life. Unless the hotel has a bus to Suvarnabhumi.

7:25 flight, 2 hours earlier there, means 4am wake up (or coming straight from a party) and catch a cab. Assuming the OP is in BKK along the main roads.

I've never had a problem with hotel reception suggestions on time to leave for the airport. They're usually up to date on travel times and traffic situations.

The OP didn't state where he was staying so a hotel it's the most likely place he will leave from.

Do you have any suggestions or the phone number for a radio taxi company or is that thinking too much?

Domestic or international departure? From BKK or DMK? Hotel location?

Assuming an international departure from BKK and a hotel in Silom/Sukhumvit a 04:45 - 05:15 departure is recommended.
