land in Changi, within 30 minutes
1. gotten your luggage
2. immigration all settled
3. you're already on the road to your next destination
4. you're also already within the city

land in KLIA,
1. you need 15-30 minutes for your luggage
2. another 1-2 hour for immigration clearance (this is from tourist perspective that cant use autogate like malaysians)
3. another 1 hour to travel to KL


KLIA is the worst airport in this region to transit. go to reddit & you will see international tourists advise to not transit here.
imagine transit from KLIA 1 to KLIA 2, this process would take at least 3-4 hours (good luck catching your next plane)

use different airlines.
whichever airline cheapest will always be traveler's preference.

tourists would think Terminal 1 & Terminal 2 works just like how Changi's different terminal works.
but noo, KLIA 1 & KLIA 2 are in separate building, separate immigration, etc, despite using the very same runway.
