Even though it seems to be getting harder to use air miles to get free tickets , its still worth it when you can use them.
You can often use them for other things besides tickets. Sometimes you can cash them out or even purchased suit cases so if you have a miles card check their website to see what else you can use your miles for. You can also use them for upgrades so if you do end up purchasing a coach class ticket see if you have enough miles to upgrade to first class.
Check out this website to review different miles credit cards.
Hotel’s have rewards credit cards as well.
