It's also my understanding that jetBlue has decided on ORD and ruled out MDW. As mentioned previously, ORD is actively trying to pull jetBlue in. To date, they haven't been able to come up with gates that jetBlue actually wants. There was a similar problem at BOS that took more than a year to resolve. However, as we are all aware, that problem was indeed resolved and jetBlue will soon begin serving BOS - not a secondary airport. Look for the same to happen in Chicago. If it takes another year, jetBlue will simply wait. There are plenty of markets available to them in the meantime.
