Our taxi ride from Lat Phrao, where we stayed, to Suvarnabhumi Airport, costs about 235baht(RM23.50) plus 25baht toll charges. It took about 35minutes to arrive airport.
When we checked in, the ground staff allocated two of our 4 seats together whereas the other two were separated! And we didn't pay for a pre-book seat. :p
So I said, " We have kids and the young one will cry, looking for us ".
The ground staff re allocated the two separated seats to "hot seats" (first five rows with red cover headrest),which was not occupied for that flight, explaning that she could only did this if they were kids involved.
Hot seats passenger got to board first. (not a big deal! )
