AD PLACEMENT — CONTEXTUAL
A free inter-terminal shuttle train connects T1 and T2 in about 15-18 minutes of ride time, running every 5-10 minutes, with additional walking and processing time bringing total transfer time to 25-35 minutes. Passengers connecting within the same terminal move through dedicated transfer corridors without needing to re-clear immigration, though a secondary security screening point exists at the transfer level for international-to-international passengers.
