It's nice that a company rep escorts you from the hotel lobby to the car/van with a driver and takes you into the airport - right through the correct security lines and points you right to your check in line...basically holding your hand which is sometimes nice when you are in foreign country unfamiliar with the language/airport etc.. Also they arrived early and were waiting in the lobby for me which is great.
Both drivers who were picking up and dropping us at Chiang Mai Airport punctually were quite courteous towards us. Before departing to my home country, someone (one of their drivers' assistant) was asking rudely for money without showing his licence card. Therefore, we doubted about his licence but I presented a viator voucher to him, showing that it was already pre-paid. Hope every driver should possess their licences to show them to the tourists and also cultivate their courteous attitudes towards them in future.
I was very happy with the transfer. I had booked my flight for 7am and needed a pick up from my guesthouse in Chiang Mai at 5.45 am.A driver arrived at 5.30 am, helped me with my bags at the airport. I would highly recommend this service to anyone who needs a transport from or to the Chiang Mai airport. Service is 24/7.
