Consolidating Miles
 

I have a few miles with United, American, Delta, Alaska and quite a few with Continental. Does anyone know how to consolidate these miles?

My suggestions is dump them in Hilton's program you get 2 points for every 1 airline point. Then just use them for rooms. Anytime you pour them to hotel then redeem a airticket you loose a lot.

randel8825, I agree with milesrus. If have accounts with multiple carriers, you can open a Hilton HHonors account and transfer your airline miles into HHonors frequent guest program.

Once you've transferred your airline miles, you can use your HHonors points for hotel stays, car rentals or merchandise, although, you can also request an airline award with the Hilton program. You'll lose some value in transferring your miles to HHonors points when redeeming them for an airline award though.
