I for one will not use the web check-in. WHY?! because it is taking jobs away. We all may b1tch about waiting in long lines for our boarding passes and checking our luggage, but remember, this is taking jobs away from people.
I will also NEVER use a skycap. Again, this is taking a job away from those USAirways employees that keep treating me quite well at PIT and the other airports I fly out of on a daily basis.
This is just another attempt of the airlines to downsize their workforce not enhance it. Yes, the kiosks are useful, but they still have to me manned by an agent behind the counter. Albeit, not as many as there used to be.
It seems the TSA outnumber the airline employees in the airports lately. Take a look at PIT and see the ghosttown it has become.
