What is a "milk run?"

Okay, this is a question for my roommate who’s doing some research, so for any clarification I’ll have to go and chat with him.

Does anyone know the definition of a “milk run?”

Does anyone know a history of said milk runs?

Thanks in advance.

At my house it’s similar to a beer run. It’s a late night run to the store to buy milk so the kids can have it with breakfast. Chances are we’re talking about two entirely different things.

Sometimes its an fund-raising event (including an actual run) sponsored by a local diary, to promote milk drinking as healthy. Sometimes.

In Catch-22 the bomber crews used the phrase to describe an uncomplicated mission, where they could fly straight to their target and drop their bombs and fly back without anyone shooting at them.

According to this site, it’s an airline route that stops at small cities:

I guess the analogy is that, like going to the store for milk, it’s a short trip making minor stops. Incidentally, you can find definitions yourself easily. Put the phrase you want and the words “definition” or “etymology” into Google. There’s also some online dictionaries out there you should put into your bookmarks. Didn’t you find this term in any dictionaries (you know, ordinary books, not online ones) you checked?

Merriam-Webster says milk run is “a short, routine, or uneventful flight”, probably derived (circa 1925) “from the resemblance in regularity and uneventfulness to the morning delivery of milk.”

In other words, a simple commonplace task with no expectation of surprise or difficulty.

I have a two-year-old.

What?

When using the phrase “milk run” I’ve always heard it in the context of Wendells airline routes.

I assumed that it came from the daily milk delivery of days of yore (or days of now in UK). A “milk run” was a route that had many stops along it. It may be a simple route, but the length of time to finish it is long due to the stops that must be made.

I refer to some of the the commuter trains schedules as “milk runs”. The train that I try to catch every day is an express to my station. If I miss it, then I’ll have to take the “milk run” which stops at all stations and ends up taking an extra 20 minutes to reach my stop.

In my mind (as a daily commuter) it is what cantara said in his/her 3d paragraph.

We have “milk trains” in Sweden too. However, they have nothing to do with delivering milk, but the stops made when collecting the milk from the dairy farms.

I’ll bet our pal David Simmons has something to say about milk runs. I have the impression that a lot of those missions which were originally percieved to be easy didn’t turn out that way at all. Therefore I suspect that there may be a post-WWII thread of cynicism woven into the meaning of the term.

I’ve tried to research this question myself. My best guess is that it does indeed date back to the 19th century, when trains brought in milk to cities from the surrounding farms. These would be short and normally uneventful trips, very routine because they would take place every single day on a regular schedule.

Later usage in airlines probably does relate at first to their usual, routine flights and in WWII to flights that were considered safe and easy compared to combat runs. No doubt, though, that Sofa King has a point in that some of these turned out less safe than others, leading to a cynical take on the phrase.

Here area couple of cites that reinforce this interpretation, without shedding much light on the origination of the term.

Thanks everyone! I think the “short, easy mission” definition is what my roommate was looking for. You guys rock.
