Traveling This Weekend

Hello all, just wondering if anyone has flown out of Lambert the last few days. I am flying out Sunday to go to San Francisco and finally Taiwan and I am kind of getting worried about how early I need to get there because of the spring break rush and the partial government shutdown.

My flight doesn't depart until 6:50 a.m. Our group of about 15 was planning on getting there at 4:30. Will this be enough time?
