For us, meet schedules have actually been coming out earlier this year than in previous years. We have gotten the first four meet schedules around four weeks out or earlier, even for one very small local meet. One schedule did change about three weeks before the meet. I don’t know exactly what is behind the increased lead time, but I appreciate it.
For a big travel meet, there should be an expectation that schedules will be finalized about six weeks out so parents have time to make flight arrangements. For the parents, who are the meet’s actual paying customers, it would be much less of an inconvenience to have uneven session sizes due to scratches than to have to change travel plans at the last minute or book tickets to be in town for the entire meet.
