I quit flying into KLAS (McCarren Intl, Las Vegas) when Signature charged me $4.50 last summer. KVGT (north LV) was in the mid $2 range at the time.
AND a $45/night for tie down, for a Bonanza (KVGT is $6).
Throw in $20-30 in tips coming/going for rides, linemen, etc., and I told my wife that's the last time, inspite or their great service. They aren't worth it to me.
Too bad...I miss flying in on 19R along the strip......
Anytime I see Signature as the FBO on field....I look somewhere else to land.
