Can I transfer Airline miles to Marriott points?? Which Airlines?? I am short about 25,000 pts. for a stay in Oct. and don't see any charges that hefty coming along.
Any help available??

In general, I don't think any of the airlines directly transfer their miles into Marriott points. One tool that might help you find some alternatives might be the Mileage Converter from the Insideflyer website.

i find the best way to do this (either route miles>points/vversa) is that if you purchase a 'package' ... you can use the surplus to get incredible transfer rates.

I've done it about 5 times from Marriott to book a resort and then push 50K points to AA miles and did it once from AA to marriott when i had more there.

It was VERY attractive - and the nice feature is that they just 'deposit' the equivalent in the other bucket ... so you don't to even immediately use them.

but it's by far the most beneficial to transfer them. You just basically have to committ to using something. But it sounds like your trip has already commited the miles to a flight - now you're just trying to lock up the rooms. I'd call AA reward services and you might be surprised.

I've LOVED that loophole going the other way from MR to AA.

Marriott allowed miles to points transfers ten years ago then discontinued that around 2001?

Hilton still has some airline partners for miles-to-points transfers. That used to be a great deal when 50,000 miles earned a six-night award stay using a GLON VIP award (2003). Not so great a deal anymore.
