As always most often than not folks buying the revenue ticket are concerned about getting the lowest priced ticket that works for them without any consideration to airline miles earned. For e.g. you might find a flight which has a lowest fares that works for you but does not earn any miles as the ticket might be "highly discounted". But unless you are flying airlines which does not have "any" partners or does not belong to any "alliance" there might be some opportunity to earn miles even though the airlines you booked your flights on does not provide any such mileage credit. Make note of below pointers which would help you earn those miles!
Case 1: You booked the Cathay Pacific (CX) flight in "S" class which would not be earning any CX miles:
Knowing that "S" class would not earn any miles on "CX", you would want to find out if any of the "alliance/partners" provide any mileage credit for "S" class of service. Doing a little research you will see that "British Airways (BA)" provides 25% credit of miles traveled in "S" class while "Finnair (AY)" provides 50% of miles traveled as of this writing. You would need to check out the "relative value" of 50% earned miles to 25% earned miles and decide accordingly. But just using the Frequent Flyer membership number of either of these programs would be a great idea for crediting your miles to them rather than not receiving any miles. You can check out the "chart" for BA here and for AY here.
Case 2: You booked the Qatar Airways (QR) flight in "V/W" class which would earn 25% of actual miles:
Doing a little research you see that Qatar Airways (QR) is a "partner" of US Airways (US) (One World Alliance member) and Asiana Airlines (OZ) (Star Alliance member) which earn 50% of actual miles flown as well as give you access to use those miles for redemption on either One World or Star Alliance. Thus becoming Frequent Flyer (FF) member of either of these two and crediting your miles to them you would not only get a better earning rate but also access to other "alliance" airlines awards. You can check out earning for QR here, US here and OZ here.
Thus checking your options for mileage credit can open up more opportunities than you can think of :)
