I know that flying DL from USA-MEX in F does not qualify for Sky Clubs, but how about other ST lounges? The ST lounge access rules state that International Travel excludes customers traveling between US and the Caribbean, but what about Mexico? I have a flight from LAX-CUN and I am trying to find out if that would qualify for the KE lounge? The rules seem clear as mud. Is CUN considered to be part of the Caribbean? Are the detailed rules published anywhere on the ST website?
