I had 3 refunds last week due to changed plans and a fare difference and received all 3 refunds in 3-5 days (5 days being the longest). These were business days so 3-5 days is really 3-7 days. A week is not a long time to wait for a refund. When you consider that a it takes UA 2-3 days to collect on a cc purchase (time from when its a "hold" to when its a purchase). I'm not sticking up for UA because they don't need me to sick up for them. A week is a normal time to wait for a refund. That's how long you'll wait for a refund from Bloomingdales too
Now, if it was 2 weeks and still sitting in a que, I'd be all over it but a week, nah. I'm very happy w how my refunds were processed
