There are no nonstop flights from the United States to the Inverness Airport (INV), which only receives flights from other European cities. To fly into Inverness, you need to book a flight to Scotland with a layover in London (Heathrow or Gatwick), Manchester, Dublin, or Amsterdam. Keep in mind that it may require several flights on multiple airlines. Alternatively, you can fly into Glasgow or Edinburgh and travel directly from there by train or bus to Inverness.
