I think this might become a little more common. We continually take delivery of more 700s. All the up-gauging cannot necessarily be accounted for when the bids are prepared.

This will be especially true when we start swapping 200s for 900s. Route-wise, more 200 routes will get shifted to 700s, and some 700s to 900s.

Wouldn't be surprised to see more up/down swaps even during the 200 trips in the near future. It's only the LCA 200 trips that scheduling has to worry about...
