Matt,
Wecome aboard. If your user name is anything to go by we are in the same area. Unfortunately, most of the regular Scheduled traffic does not appear on the map so unless you are in line-of-sight to Inverness or one of the Military bases then you will have difficulty. Keep looking to the Southeast and you will see the northern oceanic route. Currently tracking Air France A332 but to cloudy to see it. Air Canada, Delta, Lufthansa, KLM, BA & Virgin are the main users of this route on some days of the week. To the Southwest you can often pick up Ryanair and SAS traffic again you need a good line-of-sight. Good spotting.
