i found that theyre not that bad in a crunch time. technically they are worth 1 cent a point but sometimes they r worth more
for ex, we had to make a last minute flight, on aa or delta i wasnt seeing anything in miles below 50,000 and the prices were $700 and up for a domestic ticket.
it ended up being about 50,000 ty points bec they calculate the points before taxes. if ur earning 2 points for every dollar spent (and for gas and some stuff 3 points) that ends up being pretty worth it
so in the end i had 90,000 points and ended up getting 2 flights, each worth about $700 but would have been at least 100,000 pts on aa or delta
however when theres better mileage availability then their points r not worth so much
