Things are going well.

All of the following things work: Customer chooses one way, round trip,
or multiple city. They then are directed to a flight search page where
they can choose direct flights to their destinations (I don't trust
myself to copy/paste the Indirect Flight Code -- Can you do this Ben?)
The customer can finish choosing all the flights they want.
When they are done, they are redirected to another page which pulls up
their first journey. Tomorrow, I'll code this page so that it does
calculations and allows the customer to pay (and maybe select a seat).
Let's not get too excited. The customer can still choose flights that do
not go in date order. Also, figuring out how I will keep track of every
customer and their age and etc. to do pricing will be difficult. Also,
miles and letting them pay with those.
