WBurcham-- Glad to hear you finally made it back with the wine. I think that you suffered from a case of a poorly informed/trained agent... about 1 year ago I had to go through a sort of crusade against some sloppy gate agents at the various US airlines because they were enforcing a non existent rule... the 4 liter (or 2 liters is the amount that some agents had in their head) rule is related to flammable liquids.... this includes hard liquor like Vodka or Tequila. Wine will not light up even if you hold it up to a flamethrower...... but some agents just assume that wine is like the hard stuff and that is the crux of the issue.

The EZE security excuse is 100% bullocks.... If you have the name of the agent or something, do PM me as I know the senior management at Delta here in Buenos Aires and I would love to take this up with them.

Good for you for escalating this to a supervisor... ^
