Attempt at a phantom version of flights

Instead of using zombie, use phantom to possibly execute the same code
path as zombie did to get the flight costs.  However, there's
definitely some learning I need to do, or find another solution, since
the phantom path doesn't seem to wait after events are triggered
(clicks that change pages), so I'm forced to add sleeps.  Because of
this, it doesn't seem like the solution that should be chosen.  Maybe
there's a better one out there?

Find flight prices for multiple months

Using zombie, find the prices for the current month, the next month,
and the month after that.  The future months should follow the same
pattern as the last month recorded.
