Word to the wise: If a Delta ticket agent swears for 10 minutes that "Fly for Less" tickets are refundable (Fly for EVEN Less are not per the webpage, but Fly for Less are supposed to be), and you buy some as a backup for your family vacation because Delta doesn't give you even one PS for family vacation a year, and you try to cancel them 3 day early to get your $$ back as promised...
... you're going to get seriously bent over.

And when they decide to charge you the "change fee" of $150/ticket instead of the cancel fee they promised would apply if $29 per ticket, and just give you a credit towards some future flight instead of the actual refund as promised, don't even THINK about questioning them.

And if you even TRY to discuss it and bring up the fare rules and pamphlets linked to the Fly for Less page to support that you should get your $1900 back as promised when you bought the "refundable" tickets, which you wisely printed to be sure you could get the promised refund, you're going to get threatened with having your Non-rev privileges being revoked.

Last time I EVER try to fly on Delta for $$, or try to give them my business. That 20% "savings" as an employee was the most expensive ticket I never used in my life, and getting threatened by a ticket agent to shut up and take the loss was just unbelievable. NOT a huge fan of my company just now.
