Population of the island is about 168K. Most live in the vicinity of Kahului population 28K, which has the airport and main harbor.
Lahaina is quite small, population of 12,702.
Although Lahaina was not the only fire, I’ve not heard that any of the more populous communities and/or infrastructure were burned. I’m sure the TV cameras would be there if they were.

By far the best way to travel between Hawaii’s islands is by plane. In almost all cases it’s also the only way to travel too. There are three main airlines that operate regular daily flights between Hawaii’s main islands, Hawaiian Airlines, Mokulele Airlines and Southwest Airlines. Each airline operates over a hundred flights a day between Hawaii’s islands and there are almost hourly flights between Oahu, Maui and Kauai. There are also daily though less frequent flights to the smaller islands of Lanai, Molokai and Kauai too.
Needs more illegals.
