I think it is more of a corporate vision.


I won't hold my breath, then.

A military plane is often very old. The one we were on still used propellers. It was basically a cargo plane for a test we were going to do, with a few rows of seats in the front. They pressurized it to 10,000'. She had blown out both eardrums in a SCUBA dive in Panama so she was in a lot of pain for the entire trip.


8,000 ft is only a little higher than MEX City. 10,000 ft is higher than even the highest cities in South America. That's a major difference.

They say the human blood begins to lose it's saturation of oxygen in the hemoglobin at 7000' where air pressure is 22.8% lower than sea level. Since you are not normally exercising on an airplane most people are fine at 8000', but would be more comfortable at 6000' or lower. Obviously people who live in Mexico City have an advantage. At 10,000' the air pressure is down 31.2% and at 50% at 18,000' .

18,491' is altitude of summit of Pico de Orizaba
10,152' is the altitude of Leadville, Colorado, the highest incorporated city in the USA.
8,563' is the altitude of Metepec (a mid size city East of Toluca, Mexico)
11,919' is the town of Raíces , Mexico which has a population of under 500

The informal name "death zone" for 26,000' means you are only at 1/3 sea level pressure. It is commonly said that you cannot acclimatize to this little oxygen, and you will ultimately die. Of course it would be cruel to do experiments even on animals, so no one really knows that for sure.

It's rather a contiguous part of Toluca. I've been there on business a lot of times.

In other words, I never feel any trouble with the air pressure in a plane. The lack of humidity is something else, especially as security theater requires I pack my moisturizer in a checked bag.

Yesterday around 11:50 PM or so, I caught an AM 737 on approach to MEX, labeled as going to Tijuana. Odd. The route had it flying towards Tijuana, then doing a 180 (more or less) back to MEX rather far to the northeast, near Durango.

That was really odd. I searched for the flight on another app, and set an alert. So I could track it, and keep the flight number, later on. This app reported it landed around 2:30 am, MEX time, which would be barely possible if it landed in MEX, refueled in record time and immediately took off again.

I'll do a search of airline incidents later and see if I find something. It may all be an app glitch, after all.

This plane landed around 2:30 am. Is this the one?

Oh, I forgot to post the flight number.

It was AM 194 MEX-TIJ

I mentioned this before, flight numbers don't seem as important to travelers anymore.

Plane broke-down. It took off 22 minutes late and returned to Mexico in 77 minutes. I doubt that would give you enough time to make it to Durango City and return.
That seems more like you wouldn't get further than Aguacalientes.

The plane did not fly the next day at all, as both flights were cancelled.

I'm not sure what that is, as it landed in MEX at 11:09 PM. Possibly the app get's it data from something that was reporting the plane coming in for maintenance.

AM last plan to TIJ leaves at 10:35 PM, so those passengers were screwed for the night. They may be skittish and not want to fly the next day, so hopefully AeroMexico put them up in a nice hotel and gave them meal tickets. I have never been on a plane that came back.

The routes on Flight Radar are often weird. Now, no doubt there are some odd routings now and then to avoid storms and such, but often the info is just wrong.

Still, a return after 77 minutes explains what I saw.

One time I nearly was diverted to GDL. That's the extent of my misfortune. Another time on Interjet the plane went back to the gate right after push-back, but ten minutes after that we were on our way. I've never been bumped, either.

People don't get bumped that often in the States. There is usually someone who volunteers to give up their seat. My best "give up your seat" experience was one where my luggage was already on the plane. They gave me $400 to take a later flight, but I made a connection that I shouldn't have by two minutes, and I beat my original flight with my luggage by 30 minutes. I had to wait for my luggage to arrive. So I earned a $400 credit and lost zero time.

I only got bumped in Zacatecas, and I was about an hour early for the flight. I asked the guy how I could bumped if I was so early. They said that they didn't offer compensation to people who gave up their seats in Zacatecas, because they never had volunteers.

It's a bad place to get bumped. There are almost no options as the only real domestic routes are to MEX and TIJ.

Tuesday, I took a flight from Chicago to Detroit. The departure was delayed slightly because Detroit was in a ground stop due to fog.

We got to Detroit, attempted one approach, then flew to and landed in Pittsburgh.

They intended on refueling there and sending us back to Chicago. We sat on the plane on the ground for over 2 hours while they worked out the computer dispatch, manifest, weights and balances, and got everything approved. They put us up in a hotel overnight and gave us meal vouchers.

Most of us were then re-scheduled for a Wednesday evening flight to Detroit. All earlier flights were fully booked. After being on standby for the first two Detroit flights, I got on a flight to Flint, Michigan and got picked up at the airport there.

Not a fun day(s).
