I already use the EF and that's my problem. When I find a good deal, I never find the class that I need/like.

For example: on this week I was looking for a flight between GRU-AMS using Aeromexico (they have this route). The ticket on E class just give me 5K miles on DL, instead the Q class give me 10K for $150 more. I found the flight but I round around a lot of OTA's and no one give me the same class, even with free seats on EF.

Thanks
