hi hope someone can help me, we are coming to thailand on 19th october with thai airways from dubai to bangkok & then onto phuket, we have done this trip loads of times & the thai airways flight arrives at 8am & the connecting flight was always at about 9am, we last done this in march of this year but now I have just called thai to book our flights for october & they told me that the connecting flight does not now go till around 2pm & another even later

because we dont want to hang around for so long at bangkok airport I am thinking to take air asia flight instead as there is one that leaves at 10.50 am however I havent booked it yet as I am a little concerned about the 2 diff airports & if 2.5 hrs a be enough time to collect bags from thai exit the airport then re check in for air asia. I was not aware there was 2 airports but I think they may be some distance apart???
Pls help someone as I wanna book all this, basically will the air asia flight depart from the same terminal/airport as my thai air flight from dubai will land in
