See Fugazy Travel Bureau, Inc. v. CAB, 121 U.S.App.D.C. 355, 350 F.2d 733 (1965); Railway Express Agency, Inc. v. CAB, 120 U.S.App.D.C. 228, 345 F.2d 445, cert. denied, 382 U.S. 879, 86 S.Ct. 162, 15 L.Ed.2d 120 (1965); McManus v. CAB, 310 F.2d 762 (2d Cir. 1962).

The New England Division Case, 261 U.S. 184, 201, 43 S.Ct. 270, 277, 67 L.Ed. 605 (1923); see FPC v. Natural Gas Pipeline Co., 315 U.S. 575, 583-585, 62 S.Ct. 736, 86 L.Ed. 1037 (1942); McManus v.

C.A.B., 286 F.2d 414, cert. denied, 366 U.S. 928, 81 S.Ct. 1649, 6 L.Ed.2d 388, rehearing denied, 366 U.S. 978, 81 S.Ct. 1918, 6 L.Ed.2d 1268 (1961).
