I know. That's what's ridiculous. I've actually dealt with this situation before - I used to have an agreement with a local travel agency that allowed me to directly book my own flights through Amadeus. Sometimes when my travel schedule got too busy, I would miss schedule changes and the travel agency wouldn't tell me because they thought I already knew, so I've missed flights on UA and AI due to sked changes. Despite the fact that it was completely my mistake, UA rerouted me on an OAL to get me where I needed to go, and AI promptly refunded the ticket. While it was my responsibility to be aware of the schedule change (especially since I was the travel agent who dropped the ball), it was the airline-initiated schedule change which caused the problem in the first place, and the airline was willing to do what they could to fix things.

That's the basic level of customer service I'd expect from an airline. Mistakes happens sometimes, but in my experience most airlines are typically understanding and helpful in making things right*. And on the converse, when airlines make mistakes and cause delays, I'm understanding too. That's what inspires loyalty and a strong customer-business relationship. LG clearly doesn't understand that.

*In my personal experience, LH and BT are exceptions - they've been terribly inflexible when problems have come up in the past. Maybe it's a cultural thing, and I'm too used to flying in the US and Asia.
