BOS-HYD is going to be $1400 +/- 10% on United but will yield ~15000 UA miles from the flight + 3000 miles from the card. If you price the miles at approx 2cpm, that's $300-$400 back.
So if you use miles, its more expensive than paying $ for economy unless you value your miles very lowly.
PM if you have questions, fellow Boston guy.
