Didn't see Delta there and what I saw would make the original question a dictionary answer.

To best explain what the diff is between Delta And CAL, I got these facts for you: We have NO scabs in Delta, people working for Delta like Delta, in Delta people are not saying it was better at the regional they left from. If upgrade is your number one priority, you live in CLE, or simply enjoy scabs - go CAL. Just my 2c worth...
