If your flying to Ak from the lower 48, your probably stuck using a major air carrier like Alaska, Northwest, etc. However, for travel to rural hubs in Alaska from Anch. or Fbks. there are smaller carriers that also offer service. Both Frontier Flying Service and Pen Air offer travel to most all the hubs in this state. Additionally, they don't charge extra for guns, etc. and you don't have to go thru security to get on their planes, as they use smaller turbo props.
If your planning a trip to Alaska, check out these carriers. Their prices should be competitive as well.
