Not sure why all the bloggers like the 1,000 or 1,500 mile bonus offers on a 3 day rental. Most rental car agencies offer a free day on a 3 day rental. So, unless you are on a VERY cheap rental, the free day is going to be worth more than 1,000 or so miles.
There are several ways to evaluate these offers. And one way is to consider this: if you decided to use some AAdvantage Miles for a car rental, cheap tickets to trinidad from new york you d likely need to redeem at least 5,000 miles for a single day. So if you compare a free day rental (pardon the oxymoron) to 1,500 miles, the free day provides a better value.
Of course, some may find the miles more useful than the free day rental, it s really just a matter of preference, b ut Mark s got some very solid advice, so I thought of him when I came across this offer from National cheap tickets to trinidad from new york Car Rental:
Rent a compact through full-size car for a minimum of 3 days at any participating National cheap tickets to trinidad from new york location in the United States. Save up to 25% and earn 500 American Airlines AAdvantage bonus miles plus receive One Free Weekend Day with National. Saturday overnight keep required.
Also, National Car Rental is celebrating 25 of their Emerald Club loyalty program., cheap tickets to trinidad from new york and to celebrate they ve teamed up with The Weekly Flyer to give away two $25 gift cards to Points, cheap tickets to trinidad from new york Miles Martinis readers .  All you have to do is share how you traveled 25 years ago.
I always assumed that those traveling on business expenses preferred to get themselves miles rather than save their company the cost of a days car rental. In fact, I would be interested in hearing other reasons for people selecting miles as car rental with a miles offer costs A LOT more than alternatives. For example, I recently look at a 3 day weekend cheap tickets to trinidad from new york rental in Atlanta. Following links to miles offers got me about US$65 a day. Going through Costco got me $28 a day for the same car class. I am spending my own money so will go for the cheap daily rate everytime!
I prefer the miles, personally, because I m usually traveling on business and I m never the one paying for my rental. When I travel for myself, I almost always end up someplace with excellent public transportation and seldom rent a car.
