I agree..if you did it on roundtrip,the computer is going to catch you and void your return(with no refund!)..it happened to me..the way it was explained to me was you buy a ticket from point A to B with a stop between..if you never went to point B..but only to the stop between,you have voided the contract between you and the airline..I am not making a debate here,I am just passing along information that happened to me..it is refered to as "Hidden City" ticketing and I was Busted by CO for it and didnt get a refund..I wouldnt reccomend trying it,but maybe it will work on a one-way ticket where you dont check bags..otherwise,forget it. @:-)
