What hawaiianSF, says..
A few laggy lobbies, but nothing out of the ordinary. I know i'm tempting fate , but imo, it's been one of the least laggy periods, post patch, i can remember.
There are a few things you can try which "may" help your situation, but no guarantees.
Play on a wired connection.
Check and re-check all physical connections too and from the Xbox/router
Clear system cache
When you feel the LAG Monster creeping up on you, back out to the dashboard, (from the lobby, not in game ), and test your connection from "System settings". Restart your session, and see how it feels.
It's possible a geographical issue is interfering with the quality of your game play and nothing you do will solve the issues. Give the suggestions above a try as a starting point, they're quick and easy and they certainly wont make the situation worse.
