Chartered from Jackson to San Jose this past Monday 07÷28÷14 on a flight that at the last minute required a fuel stop making the flight over 3hrs long instead of less than 2hrs normally or commercial and utterly uncomfortable. Fuel stop required because temperature of 59 degree Farenheit at take-off was deemed too high at 4pm at the airport . How unprofessional can you get? Flew from Jackson to San Jose this winter when the pilots that had just come in turned off their engines and let one of the freeze delaying take off by over two hours. No apology, No taking responsibility. Lots of irrelevant excuses. Bad Charter experience twice in a row. No more.
