Arrival condition tells you about the last few hours and very little about the middle of the journey. A pack that is soft on arrival may have been soft for four days or for four hours.

The reasoning is more useful than the number, which is why I have shown it.

m.adeyemi, post #4: My understanding of Airline travel is a few years old and may have been superseded. If it has been, I would genuinely like to know rather than keep repeating it. Go to post

Recording arrival condition on ordinary deliveries is what makes the record useful. A file containing only the bad arrivals cannot tell you how often they happen.

That is the honest state of it as of this week.

An update on my earlier Airline travel post: the pattern held for another six weeks and then stopped, which I did not predict and cannot explain.

Post #38 and I disagree about the size of the effect, not about the direction.

Airline travel looks different depending on whether you are reading the primary literature or the summaries of it, and the difference is not in our favour.

Buchholz, post #27: Worth separating two things that post #25 runs together. The reason Airline travel is hard to answer is that the obvious measurement and the relevant quantity are not the same thing, and substituting one for the other is silent. Go to post

Everything in post #43 holds. The case it does not cover is the one I have.

I would rather this thread reach "we do not know" about Airline travel than reach a confident answer that nobody can support when asked.

Post #52 and I disagree about the size of the effect, not about the direction.

I have no financial interest in anything named in this thread and I want to say so before I comment on Airline travel, because it is the sort of subject where it matters.

Airline travel was covered in the wiki last year and the page has a review date on it, which is a better starting point than my memory of a thread.

Insulation performance depends on the mass of the coolant more than on the thickness of the box. A large pack in a modest box outperforms a small pack in a good one.

e.ferreira, post #63: What I would want before treating Airline travel as settled: the method, the sample, and whether anyone tried to find the opposite result. Two of the three are usually missing. Go to post

Post #90 answers the question as asked. The question underneath it is different.

Summer routes and winter routes are genuinely different problems, and a supplier that changes its packing between them is doing something rather than nothing.

Same conclusion as the reply above, reached differently, which is mildly reassuring.
