It will be interesting to see how the next few months go... The latest upgrade was a 2140, and I'm a little over 100 spots from that. However, there are many in those numbers that will not upgrade for one reason or another... Wanting a certain base, avoiding reserve, or perma FOs. So I really have no idea when I'll upgrade, but it could be as early as this summer. We should see upgrades fall to the 4 year mark very shortly, barring some crazy event (always a possibility!).
