That's what Delta tells me the wait time is for an agent.
No call back option was offered.
Get this - I had a flight leaving Lima for NYC on Friday, coming back to Lima the following Friday. A few days ago I attempted to change it to a Saturday departure. At the end of that transaction, it said there was a problem and I should try again later. But somehow the original reservation went 'poof' and disappeared. Now when I enter the confirmation code it says reservation not found.
