Hello there, looking to take the family to HI (Kona) sometimes around april -> june.

Debating on whether it's worse using FF for it or buy the tickets outright.
I have enough miles for 4 Coach tickets, right now they run for about $840 on AA.

Is it worse using the miles or buying the tickets outright?

We do travel a lot and if I don't use the miles, planning on using em for our anniversary (sans-kids) for 2 first class somewhere.

Thoughts.
