Don't underestimate FedEx Corp.'s air game.

Its ground segment has gotten all the attention lately, with revenue nearly doubling over the past five years thanks to booming e-commerce growth. But what arguably matters more is FedEx's air-shipping Express division, its largest unit, where rising margins are making the unit more profitable overall.

While keeping up with e-commerce growth is always important, Express's continued momentum is the key indicator to watch in fiscal first-quarter results, due Tuesday. Analysts polled by FactSet estimate adjusted earnings for the period ended in August of $2.78 a share, up 15% from a year ago. Revenue is expected to have increased 19% to $14.6 billion.

Express accounts for more than half of FedEx's overall revenue. It will get a boost from the $4.8 billion acquisition of TNT Express NV, the largest deal in its history, completed earlier this year. TNT gives FedEx a stronger footprint in Europe. Analysts at Cowen & Co. forecast TNT will initially dilute earnings. The company expects it to be accretive by fiscal 2018.

Express has shown promise of late. Its international airfreight generates revenue of $54.16 per package, otherwise known as "yield." That is the most among all of FedEx's segments and triple what a domestic package yields. Volumes also have increased.

But what has really stood out is growth in Express's overall operating income, surging about 170% over its past three fiscal years. In its most recent year that ended in May, it exceeded Ground's for the first time in six years.

FedEx shares have outperformed the S&P 500 by 3 percentage points this year. That includes a 12% surge after its March earnings report, its largest one-day percentage gain since 1993, following a strong holiday season. Wall Street has gotten more bullish, too. Some 71% of analysts who cover the company have "buy" ratings on FedEx, the highest in four years.

Granted, FedEx's growth doesn't come cheap. The company expects to increase capital spending 6% year over year to $5.1 billion to keep up with e-commerce. That is almost double what it was 10 years ago, not including TNT integration costs, which is pressuring margins in the Ground segment. Including TNT, this projection jumps to $5.6 billion, according to FedEx's latest forecast.

But it is FedEx's air strategy that should help this stock keep delivering.
