A locking flange (200) for securing an airline cart (100) can include a hook shaped flange that wraps around a pull bar (130) of the airline cart, a pair of apertures (204) on opposing sides of the hook shaped flange where the apertures reside below the pull bar when the hook shaped flange is placed on top of the pull bar, and a locking mechanism (250) for insertion within the apertures once the flange is placed on top of the pull bar. The locking flange can project below a top plane of a door (102) of the airline cart. The locking flange can be made of metal such as high tensile steel. The locking mechanism can include a cylinder having a head (252) on one side and an aperture (256) on an opposing side for placement of a lock (502) through the aperture of the cylinder.

What is claimed is: 1. A locking flange for securing an airline cart, comprising: a hook shaped flange that wraps around a pull bar on the airline cart, wherein the flange covers a substantial portion of the pull bar; a pair of apertures on opposing sides of the hook shaped flange, wherein the apertures reside below the pull bar when the hook shaped flange is placed on top of the pull bar; and a locking mechanism for insertion within the apertures once the flange is placed on top of the pull bar; wherein the locking flange projects below a top plane of a door on the airline cart, thereby preventing entry to the cart. 2. The locking flange of claim 1, wherein the locking flange further comprises a lip that rests on and creates interference with a top horizontal surface of the airline cart below the pull bar. 3. The locking flange of claim 1, wherein the locking flange is comprised of metal. 4. The locking flange of claim 1, wherein the locking flange is comprised of high tensile strength steel. 5. The locking flange of claim 1, wherein the locking mechanism is a cylinder having a head on one side and an aperture on an opposing side for placement of a lock through the aperture of the cylinder. 6. The locking flange of claim 5, wherein the cylinder further comprises a second aperture for receipt of a tamper proof binder. 7. The locking flange of claim 1, wherein the locking mechanism is a cylinder having a key mechanism. 8. A system of securing an airline cart using a locking flange, comprising: a cart having a frame and a top mounted pull bar attached to a top portion of the frame; a hook shaped flange that wraps around the pull bar on the airline cart, wherein the flange covers a substantial portion of the pull bar; a pair of apertures on opposing sides of the hook shaped flange, wherein the apertures reside below the pull bar; and a locking mechanism for insertion within the apertures once the flange is placed on top of the pull bar; wherein the locking flange projects below a top plane of a door on the airline cart, thereby preventing entry to the cart. 9. The system of claim 8, wherein the locking flange further comprises a lip that rests on and creates interference with a top horizontal surface of the airline cart below the pull bar. 10. The system of claim 8, wherein the aperture on at least one of the opposing sides of the hook shaped flange is a receptacle for receiving an end of the locking mechanism. 11. The locking flange of claim 8, wherein the locking flange is comprised of high tensile strength steel. 12. The system of claim 8, wherein the locking mechanism is a cylinder having a head on one side and an aperture on an opposing side for placement of a lock through the aperture of the cylinder. 13. The system of claim 12, wherein the cylinder further comprises a second aperture for receipt of a tamper proof binder. 14. The system of claim 8, wherein the locking mechanism is a cylinder having a key mechanism. 15. The system of claim 8, wherein the locking flange comprises a long vertical member and a short vertical member that form the opposing sides of the hook shaped flange, wherein the long vertical member and the short vertical member are integrally coupled together using an apex member that rests on the pull bar when in a locked position. 16. The system of claim 8, wherein the locking flange further comprises a side wall substantially perpendicular to the opposing sides of the hook shaped flange which is used to prevent tampering of frame elements on a side wall of the airline cart. 17. A locking flange for securing an airline cart, comprising: a hook shaped metallic flange having a long member wall and a short member wall substantially parallel to the long member wall, wherein the flange wraps around a pull bar on the airline cart and covers a substantial portion of the pull bar; a pair of apertures through the long member wall and the short member wall of the hook shaped flange, wherein the apertures reside below the pull bar when the hook shaped flange is placed on top of the pull bar; and a locking mechanism in the form of a cylinder for insertion within the apertures once the flange is placed on top of the pull bar, wherein the flange prevents tampering with a front door and frame members of the airline cart; wherein the locking flange protects below a top plane of a door on the airline cart, thereby preventing entry to the cart. 18. The locking flange of claim 17, wherein the hook shaped metallic flange is formed from a single metallic sheet that is bent and machined to conform to a shape of the airline cart and the pull bar and wherein the locking flange covers all or a substantial portion of a width of a door of the airline cart.
