Det finns en lång tråd över på Thorn Tree om samma fråga .
Även om det finns många olika åsikter, verkar det som om om båda flygningarna är från terminal 3 , behöver du inte gå igenom invandring och behöver inte en transitering eller annan visum alls.
Här är ett citat från ett av inläggen:
Please note, both your flights will arrive and depart from the new
International Terminal –T3 and no transit Visa is required for
passengers having onward International Connection. Passengers having
onward International connection wait in the transfer area, in case
they have through checked-in baggage .You will receive your onward
boarding card in the transfer area. In case the baggage is not through
tagged to the final destination, then you can contact the Transfer
desk in the International Transfer area.
For your information, the Airline personnel available at the transfer
desk in the International transfer area will be able to assist you
with your luggage. They will identify your baggage and tag it for the
next destination. They will also give a part of the bag tag for your
reference. With kind regards,
Seema.
