Wow - Is it my imagination or has GlobalPass ironed out their kinks. I use GlobalPass as my main account to collect my all my hotel stays and car rentals. In the last 4 months, every transaction has posted within 4 weeks of service. I mean EVERYTHING. This includes Avis rentals in Guam, Hawaii, Mainland USA and Canada. Hotels in Guam, Hawaii, Canada, Netherlands, Japan (Priority Club and Hilton). I am impressed.
I am still waiting on my Hertz rentals and Pan Pacific stays to be credited to Air Canada's Aeroplan. My experience in the past has been that only about 25% of my car rentals actually got posted to Air Canada or NWA. Since changing over to GlobalPass - 100% success rate. If you travel a lot and have experience in this frustrating process, then you know just how amazing this is.
I now spend less time following up. I'm happy.
