I'm about 14 years away from retirement, which as we all know generally means more of a fixed income and less discretionary money for buying airline tickets. So I've been buying points on United and American every so often when they post a deal, usually 2 to 2.5 c per point. I'm well aware that points programmes have had a tendency to de-value over time. I'd like some input around whether I should continue to do this (buying points) or just let them accrue on my credit cards and from the flights I take. Any input from FF would be appreciated!
