Elephants are scattered throughout sub-Saharan Africa, South Asia, and Southeast Asia. Elephantidae is the only surviving family of the order Proboscidea; other, now extinct, members of the order include deinotheres, gomphotheres, mammoths, and mastodons.
This in part because Delta goes directly to Sitka, while the Alaska Airlines flight usually bobs, making a stop in Juneau or Ketchikan that eats up an extra hour.
Alaska provides most of the flights in and out of my regional airport, connecting at Seattle and sometimes Portland. I've flown Alaska almost exclusively the last few years with flights via Seattle or Portland to Phoenix, Los Angeles, Burbank, Sacramento and Orlando.
