This is a list of all destinations and flights from Portsmouth (PSM) with Allegiant Air Airlines.
FlightsFrom.com is a useful website for finding airline routes and flight schedules globally. The idea is being able to explore destination opportunities through non-stop flights from a specific airport. It's a tool to set up your business meeting or weekend holiday based on your timeschedule and your closest airport.
Part of its appeal is that it just makes trips easier to plan; you see the departure times of every non-stop flight in a list.

Many low-cost carriers airlines prevent their flights from showing up on some of these (read Vayama or Google Flights) third-party travel websites. If you want a chance to view all local departures, try using FlightsFrom.com
