Sentence-ending で in a formal context


I am aware that [there is another
question](https://japanese.stackexchange.com/questions/28317/sentence-
ending-%E3%81%A7) that talks about sentence-ending で. But the example in that
question is in an informal setting.

I have an example of a sentence-ending で in a [newspaper
headline](https://www.sankei.com/economy/news/181127/ecn1811270021-n1.html):

> カウチシート初導入 全日空がＡ３８０型機就航 来年５月に成田発着で

I know what the sentence means, and I am guessing the ending で is somehow
still a variation of します, as it was explained in the answer to the [other
question](https://japanese.stackexchange.com/questions/28317/sentence-
ending-%E3%81%A7). Is this correct?




In newspaper headlines, the most important information is placed at the top,
and particles and verb phrases are often left out.  
So the で in your example is a normal particle で, rather than a sentence-ending
で. You can rearrange the word order and read it this way...

> 来年５月に、成田発着(便)で、全日空がＡ３８０型機 **を** 就航 **して** 、カウチシート **を** 初(めて)導入 **します** 。
