DFW-CUN in March, "champagne"/water/juice offered as PDB. (1:00 pm flight)
Return flight CUN-DFW had possibly the worst food I have ever seen/smelled on an airplane: A bologna (perhaps salami?) sandwich with a bowl of cabbage-based soup -or- a salt-flavored chicken breast that oozed yellow oil (and yet it was strangely dry
) served with a 'salad' that consisted of hearts of palm drowned in mayonnaise on a leaf of iceberg lettuce. Packs of snack mix instead of nuts.
