You can
earn extra airline miles or hotel points just by signing up for their dining program and attached a credit card.
The great thing about PointsHound is it's so easy to earn
extra airline miles on hotels you would reserve anyway.
There are many more ways you can
earn extra airline miles, like the dining programs run by the airline loyalty programs, and, if you feel like you need more info, you can find out a bit more about these in an earlier post I wrote explaining how to Keep Your Airline Miles From Expiring.
To convert
your extra airline miles or rail points into Hilton Honors Points, simply contact customer service for the participating airline or rail partner (see below).
That means you could earn up to 10 extra Hilton points per dollar, or
an extra airline mile per dollar.
I could use
some extra airline miles for 2 long - haul business class tickets I'm trying to book later this year.
Some credit card companies will make special offers on
extra airline miles.
