MM - Transfer Miles [New function]
I am not sure if this was mentioned somewhere else already, but I just updated my MM app and from now there is the possibility to transfer miles from one account to another (max. 35,000 miles per calendar year).
The whole is done by a partner site, so called "LoyLogic". Unfortunately it's not for free and there is a fee (e.g. 500 miles for USD 5.56 or 35,000 miles for USD 388.87).
IMO it's a good option and might help in certain situations...
