Alaska is great

The best month is June.

I've been two times in Ankorage (Sep and Feb on business)

Last check - air fare (planning to go in March) $946 Northwest Airline - Newark (NJ stop in Mineapolis) Flight - 10 hours.
Alternate flight New York - JetBlue to Seatle and the Air Alaska (the are expesnsive for non Alaskan residents - your employer can arrange a better deal)

Good luck

Go fishing, hunting and enjoy the beauty of Alaska.
