I'm sitting here thinking about what SpinDoc said, and something interesting occured to me...
Let's say it's a very heavy travel day and you have a flight that is oversold. We'll make the plane a 50 seat RJ that's sold to 53. Best case scenario: there are only three revenue pax waiting at the gate to get on the oversold aircraft.
Not all 50 of our lucky pax are checked in yet, however. Bif Smith and his wife Buffy, son Bif Jr. and daughter Muffy have got up rather late this morning and are still loading the car with luggage and trying to figure out what fast food joint to hit on the way to the airport.
Still with me? Okay, good.
The Smiths arrive at the airport with 35 minutes left before departure and are told that they will be rebooked on the next flight to their destination because they have missed the cutoff time of 45 minutes. Bif Smith rants and raves, uses some colorful language and swears he will never fly US ever again. Nice posturing, Bif old boy!
So, what good comes out of this scenario?
Well, back at the gate, Mindy the gate agent sees that the Smiths are not going to be joining the rest of the pax this morning, and now Pax A, B and C, who were waiting patiently and early are going to get seat assignments and make the flight. A, B and C are not flying together. They have different agendas and could care less about anyone else getting on the plane. But, US did get them on the plane, and I submit that three passengers getting boarded as opposed to the Smiths (which for all intents and purposes is basically ONE passenger, IMO) is better for repeat business overall.
Now, we still have a plane that is very full, it leaves on time (did I mention it had all of the bags...well, it did because everyone was early to the airport, except the Smiths), and yes, Bif Smith is POed, but he and his family will be able to get on the next flight, and eventually Bif will probably have some sort of epiphany concerning arriving at airports earlier.
This scenario works best with oversold or nearly full flights. US boarded everyone they could, and the plane went out on time. It doesn't solve the problem of moving bags faster from TSA or ticketing to planeside, but I think it's another way to look at the problem and find a bright side.
If the Smiths had been quicker to the airport, roles would have been reversed somewhat. A, B and C might have been a bit disappointed or grumpy about being booked on an oversold flight, but they would eventually make it to the destination as well. And I'm pretty sure their bags would, too.
