Does anyone know of all flights tend to change when the clocks change? My normal fligh currently gets in @0630 but in October this changes to 0800.

 

Was must wondering do all flights do this generally in which case flights will generally be one hour or so later in the winter arriving and hence will affect immigration queues in that the busiest times might change?

 

I am guessing my 0630am arrival will be equally busy when its a 0800 arrival, well thats the logic I am following anyway ?

As far as I know Thailand has no changes of the clock and on your ticket it gives local time. One would think they would already take into account the fact that the clock changes in your home country. If there are no changes in departure time during winter time then of course all the flights will be one hour later in Thai local time. 

they have taken it into account on my ticket. What was a 0655 arrival will now be an 0800 arrival. I just wondered if many other arrivals also saw the same impact ie one hour delay, and more importantly would the change of arrival mean its a busier time at Immigration etc.

Local times are always reported.  But time may look a bit odd depending on where you fly from. For example the USA in general does day light savings time, so the time clock differences will be a bid different if you flew during day light savings time or not.  So what was a 10 hour time difference between LAX and BKK may be 9 hours another time of the year.
