I travel occasionally for work, but only domestically. My flights are usually around the 3 hour range and I always go somewhere that has access to hospitals, etc. Is there anything wrong with flying while pregnant in these circumstances? Can you do it for the first and second tri but not the third?

The ability to travel will affect when I will be able to tell my work about getting pregnant. Not there yet, but I was on a business trip all week and it caused me to think of it.
