Greetings g2g- United favours "C" seriesIt is looking better now, with this merger, that a deal for the "C" series will take place for the new United Airlines. With the merger and the aggregrate number of 737's combined it is becoming more apparent that a decision will be made to shut down the older 737's and replace them with Bombardier "C" series. If the new United Airlines is being touted as the largest, then it is prudent for them to acquire fuel efficient aircraft.
