It seems not all devices along the way have a high ICMP traffic response priority, like most embedded devices. So don't assume too much about the ping times.
These planes are often equipped with air-to-satellite-to-ground radio equipment (yup, into outer space), the signal source (you) travels at a high speed too. Both factors (length of path, speed) combined with atmospheric disturbances make it very neat to have a roundtrip time of under 2 seconds.
Also, you may assume that these flights carry a number of cache mechanisms to cache images and webpages, so most of your page requests (images are especially heavy) may not be delayed at all.
I am not able to undersand the stats..please will it be possible for anyone what its about..?
@abhilashbhati - rather than stats, each line is the I.P. address (or host name and I.P.) of an Internet router that the ping had to go through in order to make it to its destination.
what is line 10, the .arpa domain supposed to mean and why it is there?
@payload .arpa is a top level domain used for infrastructure purposes, in this case to show the reverse DNS lookup for the IP 82.214.239.2. See http://en.wikipedia.org/wiki/.arpa
@payload - I was wondering the same thing.
Also, check out the Hacker News discussion: https://news.ycombinator.com/item?id=5594196
The only way to have lower latency would be to use a network of ground stations, such as what Aircell (GoGo brand in the US) does. They have ~400 AT&T cell sites they have equipment on, and form large cells for aircraft to use. This will, of course, not work for flights that need to cross large bodies of water.
Did it vary significantly throughout the flight? Someone else did the same thing last year with better (although certainly not great) results: http://pastebin.com/kHmwA20i
What about tcptraceroute?
What benefit does tcptraceroute have over MTR in this case?
In 2019 Norwegian is doing something cleaver with outgoing traceroutes (also an European flight):

And here's a terrestrial traceroute for comparison. Lots of room for improvement, eh?
