Note:

While every effort is made to keep the profiles current, bear in mind the following:

The terms under which partners participate vary considerably. For example, some airlines only give mileage credit for certain routes or fare types.

The partners themselves change often.

Even the information shown on the program hosts' web sites may not be completely up-to-date.

So, before doing or deciding anything on the basis of a program's partnerships, call the customer service number (shown beneath the program logo) to confirm the partner's participation, and any restrictions that may be in effect.
