Boeing has been the biggest beneficiary of the Export-Import Bank; they were given $48.63 Billion for aircraft last year alone. More can be read here. Though great for Boeing, this has been bad for other US air carriers, such as Delta, American, and United because of most foreign carriers such as Emirates Airlines, Qatar Airways, and Norwegian Airlines can offer lower cost tickets.
If the US does not continue to disallow Cabotage (which would let foreign air carries travel within a country and transport those citizens within that country), it could really hurt American air carriers' profits. Hopefully, the US government will continue to disallow Cabotage within the US and preserve American airline jobs.
I believe that the Export-Import Bank has its place but the airline industry needs to make sure this bank is not taken advantage of. Some possible solutions could be putting a cap on the amount of money offered to foreign companies to purchase certain items or products. This would be a great compromise both for the Airlines and Aircraft Manufactures.
