Look out for Delta with upcoming profit margin boost of 5.6%

As of now, Delta is the leading carrier among the major US airlines.

In terms of profitability, fleet management/modernisation and thus cost effectiveness, and yield management, the guys from Atlanta rule the roost.

With a careful, yet adequate capacity expansion, DAL ably defends its market share while protecting its average load factor which is outstanding for a legacy carrier in a cut-throat competition market such as air travel in the US.

There are two major threats to the company's prospects, though, that shouldn't go unnoticed. As all the major US airlines, its balance sheet is quite strained and always at risk of sudden, exogenous shocks such as another pandemic or a trade war in North America going rogue. Margins are so thin they simply cannot accomodate any major impact, so you got to be vigilant when investing in an airline even as big as this one.

That said, as long as there're no clouds to be seen, the sky's the limit for Delta.
