Datetime formatting Value Error

[djrcawley]

Issue:
When searching for flights from JFK to BOG, airline LATAM causes a ValueError in the _classify_arg.

Root Cause:
The first if statement is:

if ('AM' in arg or 'PM' in arg) and len(self._times) < 2:

Since airline LATAM contains 'AM', it tries to classify the argument as a datetime object when instead it is the name of an airline.
