Delta, JFK → MEX, MEX → JFK

No upgrades to First Class on these flights (will have to make do with Comfort+, the horror) but it wouldn’t have made a difference for lounge access anyway as MEX is basically considered domestic for that purpose. No matter, I finally got to have a (mini) bagel from Ess-a-bagel at the Capital One Lounge in JFK on the way out and got to experience a la carte dining at the American Express Centurion Lounge in MEX.
