There are a few basic rules to consider when collecting frequent flier miles- or any kind of points for that matter. These are my top three-
The first rule is to always collect them where you can. They do not cost you anything and they can add up to future flights, hotel stays, or merchandise. My rule is- if you can collect some kind of points you should – and if you are not already a member of their plan- join. It’s free and may add up to something later. The only exception to this is when the item that you are purchasing costs more to collect the points (unusual but it happens).
The second rule is to try and stick to the same points programs, so have primary and secondary programs- it is better to have 60,000 Aeroplan points, for example, then 30,000 Aeroplan and 30,000 BA. The first one can give you a trip to Europe or 2 tickets around North America; the second can’t even get you to Europe. This may seem like it contradicts the first rule, but it does not- try to use your primary program first, then your secondary one, and so on…
The third rule is the importance of understanding expiry, because you do not want your points to go to waste. Either try to use points without expiry, or if your points do expire, know the rules related to this. For example, many people in Canada collect Aeroplan points, but many are not aware that they expire after 3 years of inactivity on the account. Inactivity does not necessarily mean flight inactivity; Esso gives you 1 Aeroplan point for buying $3 of gas; so if you have not collected Aeroplan points in  2 1/2 years you can just buy $3 of gas to collect 1 point and keep the account active. Don’t find out the hard way that you have lost all of your points.
I am going to get into more detail of points programs in future posts. Stay tuned…
