Before I go spotting, I check the arrival boards on Flightradar24 for the airport I will be spotting at.
Another great website I use is https://jettip.net. This subscription-based service will automatically filter through the scheduled aircraft movements for an airport and point out the “special” movements. Here’s an example from KBOS yesterday:
The screenshot above depicts special aircraft movements at KBOS, with the “AvGeek” movements being highlighted. I absolutely love JetTip, and I highly recommend it! It’s $5/month, FYI. Have fun spotting! :)
Between 11:30-12:30, the United 787 daily route to NRT and all the Hawaii flights depart. The flight to munich(A333) and Flight to Iceland takeoff at 4:10, and the London and Frankfurt flights on B744 takeoff at 5:20-5:30. There is also flights on the 787 that go to IAD, SFO, IAH, and LAX(might be a 777). The Norwegian 787 flight is only twice a week and it departed today so u wont see it tmw. Use flightradar24 when u spot tmw to know when and where the planes depart. The A350 doesnt do flight in Denver YET…
As mentioned above, I check FR24 before spotting. If you’re just gonna be watching a bunch of 737s coming and going it can get boring pretty quickly 😉.
By using FR24, I was able to spot at the right time to see a 747 and the extremely rare 727 freighter (only 6 left in the world)
