I saved over $800 on multi-city travel through Travelocity on Delta. Sounds good so far, until I discovered Delta changed my direct CDG-MSP to CDG-BOS-MSP on a dinky plane and crappy seats. After holding for 30+ min with Travelocity, I learned they knew nothing about the change and couldn't help. I called Delta and after a 40+ min wait just to speak with someone and another 15 min with this person, I was changed back to my original flight and thankfully same seat. Does this mean customers of third party agents are the lowest of low in the pecking order? I have learned to periodically confirm my reservations and seats, however I never expected to be bumped from my original flight to a less-than-desirable connection. What gives? Is this common practice? If Delta doesn't want Travelocity business, why book it?
