I find it hard to believe that nobody has brought up the cost difference of the flights vs the value of the reward.

4.6 trans-con's (jfk-lax) on United, 3 day advance purchace, no saturday night stay = $10,409.80

8.2 trans-con's (jfk-lgb) on JetBlue, 3 day advance purchace, no saturday night stay = $3751.60

It shifts drastically with a 7-day advance and a Saturday night stay though.
