Another good source for air band frequencies is https://skyvector.com/airports, the site also has aviation charts so you can see which airports are nearby your location, the most useful are probably the World VFR and larger scale sectionals. Agree the Skywave is good for air band reception, XHDATA D-808 seems to match it for reception of marginal signals IME, sound quality is better on D-808 (bigger speaker) but does not have any scanning function (unless is is hidden/undocumented).
