Just had to deal with this with Delta. They moved my flight to a way shittier route. When they do that or make significant schedule changes, you can get your money back even on the "non refundable" tickets. I cancelled and opted for a full refund. Delta sent an email that they were refunding my card. 2 weeks goes by, and no refund. I had to call, lie about the reason for my call so I could get to a human because any time I said what I actually was calling for it would kick me to an automated system that couldn't solve my problem. I think I said I was buying a ticket or something. Then after 45 minutes hold time, get transferred, to another 15 minute hold. Eventually got to talk with someone and got my money back, but FFS, 3 weeks and a 1+ hour phone call to fix their fuck up is ridiculous.
