W: Jim White is editor of Business Travel Weekly. Jim, thanks for being on the show. Now, what kind of problems do airline passengers face nowadays?
M: Well, most of the problems are caused by the heavy volume of traffic. All airports have a limit to the number of take-offs and landings they can handle.
W: So what seems to be the problem?
M: All flights from a busy airport arrive and leave at more or less the same time. If 60 aircraft are scheduled to take off between 5 and 5:15, and the airport can only handle 120 an hour, some will always be late landing or taking-off. And if the weather is bad, you can imagine what the situation is like.
W: So waiting at the lounge or on the plane is quite common.
M: Certainly. And another problem is over-booking. If you decide to volunteer to go on the next flight out, you may get a cash bribe or free-trip voucher, but make sure you get a guaranteed seat on the next flight. And worse still, you arrive with confirmed reservation and you discover you’ve been bumped off the flight.
W: Presumably, if you choose to travel at off-peak times, there are few problems.
M: Well, there are no off-peak times. All flights seem to be full except Saturday. If there is a public holiday, things are likely to be especially busy. The special fare systems on the airline’s computers encourage more people to fly on less popular flights and this means that as a result all flights are equally full.
W: So what advice would you give to business travelers?
M: Avoid big airports if you can because there are too many flights there. Then, remember not to check your baggage if you can help it. Another thing is “Be prepared for delays. ”
W: What kind of mistakes do inexperienced travelers make?
M: One mistake business travelers make is to take far too much luggage. Take only carry-on luggage, because at most airports, you can get away with two small bags.
