This Black Friday promotion by Frontier Airlines offers travelers an excellent and economical way to travel. This is a big problem if you have some flexibility and can work with dates. Of course, routes and dates are limited, but if you're flexible and just looking for a vacation, you might want to look for this offer. Also, remember to pack the light and sit in a place where you can save money, so the frontier will pay you to carry a bag that doesn't fit under your allowance or seat! Another airline may not find this cheap fare.
