Aeroplan operates on unique routing rules. In determining whether an itinerary is valid or not, many programs use a MPM system. MPM stands for Maximum Permitted Miles, something that IATA and airlines draw up.
What is MPM (Maximum Permitted Mileage)?
The MPM is the total number of miles you can physically fly between city pairs, including layovers. These tend to be more than the actual distance between the two cities to allow for connections. You can see this info on tools like ExpertFlyer.
Most programs that use MPM follow these numbers. However, Aeroplan uses what I like to call a psuedo-MPM system. They pick their own arbitrary numbers, roughly in line with actual MPMs, but can sometimes vary enough to affect certain routings on awards. Until recently, the only way to find this out these Aeroplan MPM values was by calling in. However, there is an easy method to find the MPM limit online by yourself.
First, you should calculate the distance of your journeys is with gcmap.com. Simply put in your airport codes, and the site will spit out the exact distances of each leg you’re flying. For example, the physical distance between Vancouver and Athens is 6,106 miles. You can also use this site to determine your flight distances when calculating the miles you earn from paid tickets.
Find Aeroplan MPM Online
Now, all you have to do is complete a multi-city search on Aeroplan.com. The first leg must contain your point of turnaround – that is, the furthest point from your departing city. So as an example, I would search Vancouver-Athens, Athens-Vienna, and Vienna-Vancouver. Vienna, my stopover on the second leg, is closer to Vancouver than Athens.
Once the search results have populated, enter this link into your aeroplan page:
This will bring up a whole bunch of data on your page. Search for the MPM listed on the sheet:
For this example, the MPM between Vancouver and Athens is 10,097 miles. The actual distance between the cities (as shown above) is 6,106 miles, so you have a fair bit of leeway with connections. Thus, when searching segment-by-segment for award inventory, you can put that all together on GCMap to see if you fall under the Aeroplan MPM. You can also change your city pairs to find out other MPMs quickly.
