Yesterday my connection from PHX to SAN was delayed by four hours. Unfortunately, by late morning no options to take a flight to another CA city and connect on an AS Inter CA flight to SAN. CK rep visited me in the lounge on multiple occasions to apologize and make sure I was doing ok. Had nowhere to be in SAN so no big deal. Not sure what happened, the plane was originally coming in an hour late from EWR but the a/c was swapped out for a later flight arriving from Mexico. I find CKs are always well taken care of at PHX but of course the lounges.....
