I will be departing KGPM which is practically on the south approach to DFW airport. I need to fly almost due north into OK. Will flight following route me around the dfw airport and around several others (Meacham, Alliance, Arlington, etc.) to go north? I can stay under the bravo minimum altitudes but then I run into Class D airspace going up to 3200 ft. I could always just fly south and then head west to go around the whole metromess but that would add around 25-30 minutes to the flight and burn a lot of extra gas.
