It all depends on the two character code in front of the flight number (the marketing carrier). If you purchase UX 92 JFK-MAD and UX 91 MAD-JFK, the Air Europa earning chart applies. If you purchase a DL flight number, then the DL chart applies.
How do I know if a flight is marketed, operated, or ticketed by Delta or a partner?
The marketing carrier is determined by the two letter airline code in the flight number. For example, DL2368 is marketed by Delta and VS18 is marketed by Virgin Atlantic.
