I'm not sure what Delta is referring to but, they the company mentions they will receive the leased plane on or before April 1, so April 1 is Saturday. I assume they will have to file an 8K within 10 days of them receiving and approving the plane, but also assume they would want to PR the planes receipt. If it were me I would do that on Friday for enthusiasm to generate through the weekend. There maybe other reasons Delta is excited about Monday? That's my excitement for this thoughts about optimism about this coming Monday.
