If you know more that are not on this list please put in comments, note a LCC or Low Cost Carrier is not just a good airlines that gave you a discount.
This definition is difficult to define, however there is a list of IATA...another acronym that has all the published fares for airlines;
You have two types of Airlines.
1. Listed in the computer of the Travel Agent and sold as a published fare.http://www.iata.org
