Just in case you may have missed it before, flight attendants don't like delays any more than you do. We especially don't like them when it means our late arrival cuts our crew rest down to nine and half hours.
That's nine and a half hours from when we open the door at our arrival destination till we close the door the following day. During those nine and a half hours we have to get all the passengers off the plane, get ourselves off, go through the airport to the shuttle area, wait for the shuttle, get to the van, check into our hotel, sleep, and go through that whole process in reverse to get back to the airport the next day.
Let me repeat, we don't like delays. They make us cranky, too!
