You can buy extra weight and distribute the total amount between as many pieces of luggage as you want. Standard on almost all Condor flights, except the routes to and from the US and Canada.
The Condor website says the following (while PMI / Spain is in Zone 1):

"In general, any number of baggage items can be included in the free baggage allowance on Condor flights in Zones 1-4, 6.
If you have booked a Condor flight together with one or more other passengers and have the same booking number, the total free baggage allowance can also be unequally distributed among all of the travellers (applies to checked baggage, not hand baggage). The outer dimensions of each item of baggage may not exceed 158 cm (length + width + height). If the specified outer dimensions or free baggage allowance are exceeded, excess baggage charges will be charged. The additional baggage can be checked with your other checked baggage."

Unfortunately can only help with this but not really with the Alaska / award ticket situation.
