"And that's not the only indication to the seasonal aspect of Iraqis' migration.
Six weeks ago when my family hired a driver to take them to Damascus the fare was $110 for each passenger since finding a car to take you out of Baghdad was difficult while the return trip from Damascus would cost only $25 per passenger because drivers were ready to accept any amount of money rather than to return to Baghdad empty handed.

Guess what, the opposite is now true!
It's supply and demand 101, this change in cost reflects a change in demand on the two ends of the route suggesting that a good percentage of Iraqis who flooded Syria in the beginning of the summer season were just trying to escape the summer heat and enjoy a simple vacation, like my family did."

According to Omar it takes about 20 hours for the trip- almost 1/3 of the time waiting not traveling but waiting in lines. This distance seems about the same distance as between LA and SF which on plane the flight takes less than 30 mins and costs about $50.
