Coming back from Isaan in the evening, want to catch late flight to CNX.

Will not give credit card via smart phone. Is a seat reservation possible , say 2 hours before car arrives at Suvarna?

Is there any particular reason you don't want to enter your credit car info on your smartphone? Some Airlines will take reservations over the phone, but how much safer is it really that your trusting the person on the other end to write down your credit card info and destroy it once they are done?
