Instructions on how to search for MU (contribution by
mtkeller, thanks! I have linked from post #2):
1. Go to
http://en.ceair.com
2. Search for the route you want. Like with most award searches, it's best to do this segment-by-segment.
3. Look under "Redeem Bonus Points". If you see a "/" (see
this example), there's no award inventory in any class.
4. If you see an orange check mark, like
this example, there's award space:
5. Click the check mark to see what sort of space as done here in
this example.
6. If both business and economy show mileage rates, there's space in both cabins. If there's mileage listed for one cabin but just a "/" for the other, there's no space in that cabin.
