United miles are the best to Europe, though the routes with gold mine award space for Summer 2015 might surprise you. For Summer 2014, I wrote Route from the US to Europe via Canada for Better Award Space, and I decided to check back in on some of our old favorite routes to see if they were again gold mines for 2015.

The answer is a resounding yes.

Part I Europe
Part II Asia
Part III Africa/Middle East
Part IV Australia/New Zealand
Part V Central/South America

Europe is an absolute award chart bargain compared to Aeroplan's mileage requirement for Asian travel. After Aeroplan's summer 2013 devaluation, its award chart for travel to Asia became very expensive relative to other carriers.

Sadly, United’s recent devaluation and Delta’s unprecedented double devaluation brought Air Canada Aeroplan miles in line with the likes of United and Delta.
