When I fly international, it's more like 10-12 hours. Even assuming I had dinner before I boarded, sleep, and then wake up, I'm going to need some breakfast and a decent cup of coffee.
Then you have an even better incentive to fast, since it has been shown to reduce or eliminate jet lag [0].
I use this protocol on long flights and find it works well, getting me back in action within a day, even after traversing 8 time zones
It's not the airlines job to incentivize what some guy on the internet considers healthy habits. I want breakfast after sleeping through the night. Just a bit of fruit, some cottage cheese or yogurt, and some black coffee. Maybe throw out the dairy and give me an egg.
I already pay for that as part of the ticket price. I do not want them unbundled in a way that makes my very necessary breakfast more expensive.
Other people could say "Its not the airlens job to incentivize eating breakfast when so many people don't any more". I'm perfectly happy unbundling wasteful unnecessary gimmicks (from my point of view). And guess what? I win this one!
