Fedex Passenger ERJ-135

In reality I made this for an airline I'm running but I think I can justify together some lore.
As Delta began pulling out of Northwest's longtime Memphis hub around the turn of the decade, Fedex saw an opportunity. Northwest's wholly owned regional subsidiary, Mesaba, was on the chopping block. Other regionals operating under the Delta Connection banner would pull out with Delta, leaving behind what was perceived by Fedex management as unfulfilled demand and perhaps opportunities to grab EAS contracts which would have to be modified due to Delta's departure. The solution was to buy Mesaba from Delta absorbing their assets and moving their base of operations to Memphis where Fedex already had extensive maintenance capabilities and infrastructure. The deal ensured that the new Mesaba would interline with Delta for a period of at least 10 years and it was initially thought that the planes would operate under the Delta Connection brand. Crucially, the "Delta Connection" branding was left out of the contract which left Fedex very limited options when Delta backed out of allowing Delta Connection branded flights out of a non-hub. Fedex solved the dilemma by creating the Federal Express Passenger moniker and began operations with Mesaba's fleet of CRJs out of Memphis interlining with Delta, except the planes were painted in what was known to ground-crews as the special "Children's painting of a Polar Bear in the snow" livery instead of the Delta Connection brand. By 2011, after a year of operation, the airline had developed an industry-wide reputation for brutal efficiency which allowed for fares to deeply undercut other regionals, leading the "Fedex Pass" as it was affectionately nicknamed to be the choice regional operator for flights from small southern and mid-western airports to other small southern and mid-western airports. In the pursuit of greater fuel efficiency, the CRJs left the fleet starting in 2011 and were replaced by new ERJs of various families and a few EMBs as well. The new Embraers received the above livery after execs learned that the all-white livery was off-putting to passengers. The new aircraft lead to even lower fares, leading many passengers to fly through Memphis and then to a hub even when directs were available. Interlining with Delta became increasingly redundant as Fedex Passenger operated its own flights to hubs and non EAS cities. This style of operation using smaller aircraft, super low fares, higher frequencies, and a route network with a dearth of regional destination was dubbed Regional Low Cost Carrier (RLCC) by industry analysts. The story of Fedex Passenger's early 2010s rise proved that the economic efficiencies of a cargo operator could benefit a passenger airline.
