I downloaded the flight radar 24 app for iPad, and I am a little disappointed, as it has frequent mistakes. Any suggestions what is there better? It worked better at the beginning, but I've seen that lately it doesn't detect some flights and some areas. I was in Bogota this past week, and it was clear skies of aircraft 100% of the time! Thanks in advance for your guru input.

flightradar24.com doesn't have 100% coverage and never has.

Coverage is steadily increasing as more volunteers contribute to the network. Much of South America, India, Africa, Central Asia, China, Indonesia and the Pacific Islands are not covered. The US, Canada, Australia and Russia have improved a lot this year and there's even feed from the Faeroe Islands and the Maldives. I'm hoping someone on Norfolk Island and around Dunedin will fill some gaps down this way.

Click 'INCREASE COVERAGE' and 'i ABOUT' on their webpage for details of their origins and plans.

I also find that it is not accurate, especially on USAirways transatlantic flights. It has them going from domestic to domestic airports when it is out over the Atlantic. I also find a lot of mistakes on British Airways trans Atlantic flights.

The software doesn't deal with multi-stop flights terribly well.

Let's say you have flight XY123 which goes DEN-JFK-LGW all on one flight number. The system doesn't quite know which segment to pick up.

US Airways has a lot of flights like that, so the display can be buggy for their flights.

Is the macbook app any good?

I'm sure there are countries where it would be pretty illegal to track flights.

Not sure that I can be more positive than PA515, TonyBurr and flyingalex, apart from saying that the app relies on inputs from enthusiasts, it does not piggy-back on ATC radar. Thus the lack of "visible" aircraft for the original poster when in Bogota, reflects a lack of input rather than the lack of aircraft in the skies there.

There are difficulties with the app as already alluded to and I often notice problems with aircraft in the Seattle area, heading East and West at the one time; aircraft appearing and disappearing when clicked on and a number of other quirks.
Planefinder.net has some similar problems.

Look at it this way - we're miles ahead of where we were when I first took up following aircraft in the late 1960s, when a very simple manually tuned, limited range, battery powered (and battery hungry) airband radio cost a week's wage!
It will get better.

FlightAware, while usually useful, can have interesting results. For example, according to them, for the last few weeks, ExpressJet 4595 EWR-PVD has apparently operated with a Lear 35 for the last few weeks instead of an ERJ of some kind. How cool would that be if it was true?

FlightAware can be fun. Two other problems that I sometimes encounter are for example...1) A BA 747 going from MIA to LHR will show a zig zag geometric flight path that criss crosses most of South Flordia. but really goes nowhere. 2) I will be watching a plane and it will fly for several miles, stop for about 15 seconds, then jump back to where it was to begin with and do it again. This can go on and on. But like I said, it can be fun!

Yeah I have found Flightradar to be pretty accurate, last summer while flying from Greece back to Finland I went to flightradar using free Wifi that is installed on most Norwegian's planes and watched my own flight using it, sure was fun.

I think that most issues with FR24 is related to people expecting and presuming things without reading the description how FR24 works...

I really recommend to read these 2 pages

Sorry but Flightradar24 in Europe is great, brilliant for tracking flights and great for checking how friends/families flight is going, now gives you ETA on phone.

Enhancements the last year have made app/ site alot better and coverage is growing, you can now track flight across Atlantic instead of disappearing.

Still have odd glitch where planes appear to go in reverse or hit the turbo button and speeds up but no doubt will improve with time like everything else. Also not all aircraft are trackable.

Planefinder.net another good tracker.

As p201055r says we've come along way although I remember my dads scanner radio from late 70s/ early 80s, especially as a kid listening to speedbird001 flying over southeast England.

It seems to be down to personal preference, at least with Flightradar24 and Plane Finder. Personally I use PF, as it was the first one I came across about three years ago, and I find the iPhone app works a treat and suits me down to the ground.
I tried the free app of FR24 a year or so ago, but didn't like the look of it. I'm guessing that I would've felt the same about the free version of PF had I been using FR24 for a couple of years though. They both seem to have their glitches and limitations, but as most have said, they are constantly updating. In my experience, PF are adding new feeds and features on a very regular basis.
If you haven't tried PF, try the free version, and maybe run it against planefinder.net (which will include the full features of the paid app. (Although filters are better on the paid app than on the website). One thing the site can do that the app can't however is go back to a particular date and time in history and play traffic in real time or 'fast-forwarded'. I used this to identify photos that I'd taken en route from the Canary Isles to STN with Ryanair. Obviously being Ryanair, we weren't blessed with the wifi of Norwegian, or a route map, so couldn't track our route at the time. By using this feature and cross checking with times etc, I was fairly easily able to identify landmarks that I'd photographed, and also other aircraft that'd crossed over us etc en route. There have been several other situations where I've found this feature useful, such as identifying at a later time/date interesting 'flybys' that you've seen when you maybe don't have access to a computer/smartphone/network.
I imagine (although I can't confirm) that FR24 has this feature as well? If so, like I said, we're back to personal preference!

I happen to have an ADS-B receiver on my house. One of my servers runs an app to send the data to FR24's server (I'm T-KRDU1). Unfortunately, I haven't had the time to build a proper outdoor antenna, so I can only pick up signals within 75 miles or so.

Previous posters are correct about the thru flights. It sometimes shows the wrong city pairs on those. However, you have to remember the ADS-B signal doesn't have the flight number or city encoded in it, so I imagine FR24 does a relational lookup to a table somewhere of all the World's flights. If there are discrepancies or changes there, they're passed into the FR24 GUI. Garbage in/garbage out.

Actually in the US, it does use ATC feed (delayed 5 minutes) to supplement the ADS-B signals.

for a mobile device, Flightaware is gonna be your best bet. The only time I use flightradar 24 is to see an overview of aircraft that are over me in a certain area. Other than that, I use flightaware religiously for tracking flights that I have personally flown and also for work. I set up the alerts on my phone so when one of my flights departs its origin city heading to me, it alerts me. Pretty cool.

I have never really had any issues with FlightRadar24, and enjoy it, the other one is PlaneFinder but I find that both are the same with almost the same data online.

FlightAware is very inaccurate here in Australia, but can provide some information.

This gets complicated further when airlines use alphanumeric callsigns (like DLH6DT or BAW14L). FR24 identifies DLH6DT as DLH006, which would be a FRA-HAM flight (or HAM-FRA, can't remember which direction is odd and which is even).
