Joking aside, the problem is that the system is seeing Europe - Indian Ocean - North America (East), which is EK doesn't offer. If you were to do CDG-DXB-MLE as one, then MLE-DXB-BOS as separate one ways, that would work, yet you would be charged Flex rates for both trips.

Alternatively, perhaps you could go CDG-DXB-MLE-DXB-CDG on one ticket (which would let you get the saver prices), and then another ticket CDG-BOS.

Another option might be CDG-DXB-MLE-DXB-CDG on one EK award, a separate ticket CDG-MXP, then MXP-JFK-BOS on EK/B6.
