I flew FC IAH - CLE this past week, and the service was executed with grace, precision and professionalism; as is always from my experiences.
My Primary FC experiences are mostly PreMCO, in following lanes between airports noted.
CLE, CMH, IAH, DTW, EWR, SAN, SNA, SFM, SFO, LAX; SEA, PDX, PHX, TPA
I have yet to fly FC on UA, through PreMUA airport (ORD, DEN, IAD) or equipment (airbus).
