Long-distance airfares generally start rising in that period of time, and most people who don’t do this for a living need to request and obtain permission to travel, which can add weeks of delay. Actually, even when I was mainly dedicated to standards work for a large employer, I had to go through full approval processes for travel. It's certainly true for development engineers. However, the best we can really expect is a clear statement immediately after IETF N whether or not a particular WG will or will not meet at IETF N+1 (and/or hold an interim at a specific place and date). That makes it possible to write reasonably honest travel requests. Brian
