ATA has a pretty sweet deal for frequent travelers between the west coast and Hawaii.
You can purchase flight credits for trips to/from:
-Las Vegas, Phoenix, Oakland, Los Angeles, or Ontario, CA.
-And Maui, Honolulu, Kona, Lihue, or Hilo, Hawaii.
You must prepay for flight credits.
The cost per credit ranges between $8.64 and $11 depending on how many credits that you buy.
The minimum purchase is 150 credits for $1,650. The maximum is 700 credits for $6,049.
One-way flights start at 10 credits and go up depending on the day and season.
You can book travel with as little as 4 hours advance purchase-as long as there is a seat on the plane it is yours!
If you need to cancel booked travel-just do it at least 24 hours prior to flight time and there are no cancellation fees!
The only catch is that the credits can only be used by yourself and must be used within 12 months from the date of purchase!
