the 11th U.S. Circuit Court of Appeals who affirmed that decision after Delta appealed?
"The evidence showed that Delta induced Mesa to agree to Delta's coordinated cancellations by promising not to count such cancellations against it and then, having benefited from Mesa's willingness to extend Delta this courtesy, attempted to cancel the parties' contract on the theory that this promise was invalid as a matter of law. In light of this evidence, the district court did not abuse its discretion when it granted Mesa's motion for a preliminary injunction." 11th U.S. Circuit Court of Appeals, July 2009
