This morning I looked at some possible flights but didn't book anything. When I go back to do this, I'm told that my session has expired. I try to enter the data again for dates/route/time and get the same message. I log out and try again. Same message. I log back in. Same message. I log out and log my wife in. Same message. I give up on Firefox and go to Safari. I type in www.delta.com and it changes it to https://www.delta.com and says "Done" with nothing showing on the screen. I guess DL doesn't want my business.
