I am planning a trip in which I will spend several days in Kuala Lumpur, arriving from Singapore. It looks like the cheapest flights from Singapore to Kuala Lumpur are on an airline called Firefly, which appears to be a subsidiary of Malaysia Airlines. Even though all of Firefly's aircraft are turboprop, Firefly seems to have a good safety record with no accidents that I've been able to find. And their flights all land at SZB instead of KUL - looks like SZB is smaller, has less crowding, and is much closer to the city center and closer to my likely hotel location. So I'd imagine that a taxi from SZB into Kuala Lumpur is cheaper than a taxi from KUL.
Am I missing any factors that should make me rethink my plan to fly Firefly into SZB instead of Scoot (or some other airline) into KUL? Are there issues with going through immigration at SZB? Problems getting taxis at SZB? In-flight incidents that Firefly has managed to hide from Google?
