Pros

The hope that United will once again be the airline that passengers want to fly, employees want to work for and shareholders want to own.

Cons

Unfortunately United Airlines senior management has no concern for passengers, shareholders or employees. Their one focus has been to complete a merger with another airline. This merger will benefit no one - not passengers, not employees, nor shareholders - only Glenn Tilton and a few at the top that will stand to walk away with millions.
Most recently they are cutting back routes, planes and employees to size the airline appropriately for a merger with Continental Airlines. This is being done ahead of the merger so that all the cuts will be complete when the merger plan is presented to the justice department. United Airlines will then tell the justice department that there will be no employee cutbacks due to a merger with Continental. They will have already been done.
Additionally, many of the jobs - mechanics, customer service, pilots have been outsourced to an extraordinary degree, partly to be used as a bargaining chip when contract negotiations take place.
United Airlines senior management has a particular disdain for it's employees, startlingIy even beyond pure business dealings and to a personal level.

Advice to Senior Management

Run the airline as an airline, not as a personal cash cow. Their motives are now quite transparent and are destroying a once great company.
