WiFi Radiation In Planes – What You Need To Know To Fly Low EMF

Updated: 12 August 2017. Air travel is already stressful enough on your body. To make matters worse many airlines are rolling out WiFi in planes. So how can you fly low EMF?

Radiation and Flying

Firstly, airline travel subjects you to significant levels of cosmic rays or ‘cosmic radiation'. When I say cosmic radiation I’m referring to a collection of different types of radiation from many different of sources – the most important being cosmic background microwave radiation.

This is quite different to the electromagnetic fields (EMFs) I usually I talk about.

Cosmic radiation is a naturally occurring form of ionizing radiation produced by the sun and other stars and planets. The earth’s atmosphere and magnetic field protects the earth from most of this cosmic radiation. But when you fly, because of the altitude, this protection is greatly diminished.

For instance, flying from New York to Los Angeles exposes you to approximately 6 times as much radiation as a typical dental x-ray. A 10-hour flight across the North Atlantic exposes to more than double that amount.

EMFs in Planes

Basically there are two types of EMFs present : low-frequency EMFs and radio frequency or WiFi radiation – I’ll speak about WiFi radiation in planes more fully below.

On the low frequency side, electric and magnetic fields are created in a similar way to in a home setting, except it’s way more complicated. In airplanes electrical engineers are given free reign. Transformers, rectifiers and inverters are used liberally to change the voltage or type of current.

Sources Of EMFs In Planes

Here are some sources of EMFs in planes :

  • communications equipment
  • jet engines
  • cockpit computers
  • electrical wiring
  • electrical sensors
  • static electricity in the fuselage

Why Are EMFs In Planes Dangerous?

Firstly, a planes metallic structure can intensify the effects of EMF exposures, particularly radio frequency radiation (aka wireless). It’s called the Faraday cage effect. This radiation is trapped in a metal enclosure which exacerbates the effects of this radiation. Would you consider sticking your head inside a microwave oven when it’s turned on? I don’t think so.

Secondly, it's not just a about airplanes. It's about EMFs per se. There is a significant amount of research that points to numerous adverse biological effects of these man-made EMF exposures, including:

  • single and double strand DNA breaks
  • breaks down the blood-brain barrier
  • major organ damage
  • compromises cell membranes
  • immune system suppression

These exposures are linked to a number of serious diseases including multiple sclerosis, Parkinson's disease, Alzheimer's, cardiovascular disease, brain tumors and cancer.

WiFi Radiation In Planes

In addition to the cosmic radiation and EMFs generated from the planes' electrical and communication system, over the last few years WiFi radiation has also been introduced into the toxic soup of airline travel.

When we talk about WiFi radiation we are actually talking about devices that use radio-frequency or microwave radiation to send data back and forth through the air, wirelessly. The problem is that this WiFi radiation can penetrate pretty much everything that stands in it's path, including you.

How To Choose A WiFi Free Flight

According to a survey conducted by Routehappy, a company that evaluates in-flight amenities, 39% of airlines worldwide now have WiFi fully rolled out. Using the data from their survey I've compiled a WiFi radiation in planes analysis in the form of a bar chart, see below:

low emf flying

To compile my bar chart I took the data from Routehappy.com which shows for the worlds top airlines the percentage of ASMs (number of seats multiplied by number of miles flown) with at least a chance of WiFi, and inverted it.

When I first did this analysis, in 2016, the data was showing that only one airline, Scoot, was offering 100% WiFi coverage. Now there are three airlines offering 100% WiFi coverage; Scoot, Virgin America and Icelandair.

So in my bar chart, because in principal there is zero chance of booking a WiFi free flight with Scoot, Virgin America and Icelandair they are shown as 0% – meaning, if you are concerned about in-flight WiFi radiation exposures you should avoid booking with these airlines.

Airlines To Choose If You're Concerned About WiFi Radiation – Currently

My bar chart shows that your best chance of flying WiFi free is to book with Philippine Airlines followed closely by Iberia and Air Europa.

Three points to note:

  • You’ve less chance of flying WiFi free on U.S. airlines – 80% of their seat miles offer a full chance of WiFi as opposed to non-U.S. airlines, for which only 28% of seat miles offer at least a chance of WiFi
  • 61% of available seat miles worldwide still have no Wi-Fi compared to 69% last year
  • This data is changing fast as Airlines are eager to offer WiFi to seduce their clients

From Regular WiFi To Super WiFi

This analysis masks the level of radio frequency radiation emissions you are being subjected to. Most airlines, if they do offer WiFi, currently offer fairly low download speeds which implies lower radiation exposures. But Fortune.com reports that “passengers now demand a home broadband-like experience….so far only a few airlines meet that standard”.

The worst offender is JetBlue which is reported to be nearing completion of a fleet-wide broadband roll-out that would allow passengers to access streaming services – which implies higher wireless radiation emissions.

This WiFi roll-out is clearly demand driven. A 2016 survey of airline passengers by Honeywell Aerospace reveals that travelers now “expect a reliable connection to stay in touch with their friends and family, get work done, or be entertained.”

But airlines are not totally blamed. The Honeywell Survey found that over 20% of passengers have already abandoned their preferred airline for another company with better in-flight WiFi.

Tips For Flying Low EMF

Here are my tips for flying low EMF. Try to avoid:

  • booking with airlines that have 100% of their fleet equipped with WiFi
  • sitting in close proximity to the jet engines
  • sitting near the WiFi routers – ask the stewards where these are, they might not know but you can ask
  • the window seats, which expose you to higher levels of cosmic radiation
  • flying during the daytime to minimize your exposure to cosmic radiation – prefer nighttime flights

This might seem like a lot of things to avoid and you’re probably thinking, where do I sit? Well, you’ve really got to do your best within these parameters. And then relax…

    Very timely and comprehensive article. Just a couple of observations. In Europe some of the budget airlines (eg Easyjet and Ryanair) were holding back on wifi last time I looked (quite recently), partly because of costs. The Ts&Cs still state that passengers must turn off all transmitting devices (phones, tablets etc) during the flight. I suppose this might be waived on specific flights which are wifi’d…..
    And of course more and more airport lounges are now wifi’d, so you get zapped during the interminable waiting time.
    Airline pilots and crew are seriously concerned about the health effects and technical problems (interference with instruments etc). More excellent reasons to avoid wifi’d flights in my view. Who wants to be flown by a pilot who is affected by this stuff and is anxious about it and can’t trust his instruments? There’s a link to a paper covering this in some detail in one of the News items on the forum – https://www.electricsense.com/forum/emf-news-items/latest-news-12-july-2016/

    Thanks Lloyd, I found this really helpful

  • Lee said,

    I’ve often wondered about this, Lloyd. Thanks so much for the chart, as well as for the tips, which I will definitely keep in mind.

    I’ve heard that keeping yourself electrically grounded to the plane can reduce the effects of natural radiation. You can do this by touching the your bare foot to any bare metal part of the seat infront of you. I don’t fly enough to know for sure, but it seemed to help the few times I’ve tried it. It would be interesting to know if this helps people with EMF sensitivities

    Two discount airlines in U.S., Allegiant and Spirit do NOT offer WIFI onboard. Yay! I often fly Spirit between Dallas and San Diego. I am sure to tell the staff why, and how lucky they are!

    It seems every time I have to travel now I get sick, but fortunately, I’ve only had to deal with wi-fi on planes once, 4 years ago in America. The guy at check in was nice about it (I was lucky). He said the routers were up front (logical–where the higher paying passengers sit) and I’ve made a point of sitting at the very back since. This needs to be reaffirmed, but it also gets you away from the engines on most planes. Best of all it’s the safest place to be in a crash.
    A much bigger problem so far has been the rising radiation levels at airports, with Narita in Japan being one of the worst offenders. At most airports, the levels in the restrooms are low, so you can go “relieve” yourself there, but Narita is really kind to cyberjunkies, I guess. I bring my Acousticom, and at most airports, you can search around and find a place to sit that’s not too bad and no one else sitting there. Kuala Lumpur had reasonably low levels, and the junkies still looked satisfied.
    When I travel, I also buy a good amount of vitamin C and take it frequently. That saves me if I can get away from the wi-fi quickly enough, but with wi-fi an assumed amenity, that is becoming harder. Then vitamin C saves me from being as sick as I might be.
    Does anyone here have recommendations for other supplements for weathering these environments?
    I also bring my headnet, but aside from acute brain-buzzing exposures from the spaced out junkies in lines (and here my silver net blanket in my backpack may also be useful) I’m not sure if it helps.

    Hi Lloyd,
    Thank you for the information.
    Do you by chance know where Qantas Airlines lands on the scale?
    Living in Australia, Qantas is considered the best airline.
    JetStar is their budget airline; owned by Qantas.
    Thank you for any information.
    Kind regards,

  • Patricia said,

    Thanks, Lloyd! I have a question re window seats – are they still a higher cosmic radiation exposure if you keep the window shade pulled down?

  • fiona said,

    Thanks Lloyd. The last time I flew I felt like it almost killed me. I was so shaky and almost to the point of collapse. I now realise that was my heart and nervous system being affected. That was before I knew of wifi on planes. I am attempting to make myself stronger but am a bit worried about flying now so would love info on any wifi free planes in Australia. I thought Malaysian airlines were still wifi free too? Would you know if this is true? I did used to love travelling.

  • fiona said,

    I saw Qantas is joining with NBN satellite so are bragging this will be 10 times faster than others:( Lloyd can you please explain how this affects people on the ground? We tried to find somewhere safe to live and ended up buying 83acres in the middle of nowhere thinking it was okay. Staying in a tent I was awoken frequently with severe heart palpitations and deep chest pains. It felt like my heart was being ripped out of my chest over and over. By the morning I had a blood nose, was quite pained with difficulty breathing. I discovered we are on a flight path! Would love to know how it all works. I hadn’t even considered them previously but now can connect the pains and plans.
