My first three trips to Charleston (starting with this one), all scheduled on United, coincided with the merging of United's and Continental's reservation systems - so I had a lot of flight delays and cancellations leading to flight and even airline changes. The three trips had twelve flights, and six of those United ended up putting me on a different airline.
