Planning on a cruise anytime soon?  Like to collect Mileage Plus miles?  May as well take a look at the new United Cruises.  You can earn up to 10,000 miles for booking a cruise, and up to 10,000 more bonus miles for booking a balcony or suite cabin through March 31, 2010.  Better yet, you can earn double miles if you book your cruise with your United Mileage Plus Visa card (registration required, MPF041 is the promotion code).

I’ve never booked a cruise through one of the various airline portals, so I can’t offer any insight on the experience.  Mrs MJonTravel and I have a great Virtuoso travel agent that we like, and we book our cruises with her, even the simple ones that we could easily handle ourselves.  If you have booked through United Cruises or any other airline mileage site that offers miles for booking cruises, comment and share your experience.  Thanks!
