WT, here I'll chime in as well. On Christmas day I was on a DL flight. The F/A was smiling and happy and greeting eveyone. One of my fellow passengers stated that it was a joy to see someone from Delta being so happy at work and what it a difference it made. The FA stated that they missed being with their family and wasn't happy about working on Christmas but there were so many sick calls and so many folks that couldn't get to work because of bad weather that they were called in on their days off. What made them so happy was that they were making 12 times their rate.
The sad thing is that Customers noticed that the only way to make a Delta F/A happy was to pay them 12 times their rate.
