Lots of trimming happening in this week's episode, including United Airlines writing off $105mm on its Brazilian route/slot portfolio thanks to open skies coming into effect. The airline still made a tidy profit in Q2 '18, though.

Also taking cuts:

* Tehran is seeing flights trimmed by Air France (Joon), KLM and British Airways. Turns out the rooftop bar appeal isn't a thing. Or maybe the US sanctions not really being dropped is a problem.

* Dubai will see cuts in 2019 owing to runway repair work. If only the new DWC airport ever saw useful service levels.

* Southwest is trimming nuts from its inflight snack offerings, too; it is the end of an era.

* Gogo's stock price took a lot of trimming recently owing to questions about the company's long-term viability.

Not taking a trim?

* How about Delta Air Lines sticking with 9-abreast in economy on its 777s, a nice move for passengers, even if that is a small part of the carrier's long-haul fleet.

* And Norwegian announced that it finally scored a strong quarterly profit. Or maybe that was just a well written press release that obfuscates reality.
