On July 14, 2018 our Spirit Airline Flight #263 was delayed for over 4 hours. We were flying from BWI to Seattle, WA. The flight was supposed to leave at 7:20 AM. I would like to know what time the flight actually took off.
According to FlightAware, Spirit 263 on Jury 14 left the gate at 11:10AM, 3 hours and 50 minutes late and arrived in Seattle at 1:34PM, 3 hours and 26 minutes late (flight schedules are generally padded somewhat, so not every minute of a departure delay is always an arrival delay).
You can certainly complain to Spirit (not that they're known for being customer friendly), but be aware that the US has no flight delay compensation law, so there is likely nothing they're legally obligated to provide in this case.
