I recently had the opportunity to travel on an Airbus A380, the largest passenger aircraft built to date. The A380 has a full second floor in the hull.  It has a passenger capacity of over 550 in a typical 3 class configuration.  There are two staircases in the cabin.

Boarding can be tedious, given the volume of passengers. At CDG, we boarded through two bilevel jetbridges in the 2F terminal.  I was one of the last 100 to board the plane, and waited approximately 45mins in line.  However, after everyone was situated, the flight was quite pleasant.

The most notable difference in the travel experience in the A380 was the smoothness in takeoff and landing.  There was little indication of the ground speed in takeoff, and the cabin was significantly more quiet than in other aircraft, presumably because the hull is much further from the engines.  I felt less exhausted after my flight, and the lack of perceived motion likely contributed to the flight experience.

All of the A380′s have personalized entertainment screens.  The software suite varies depending on the carrier, but is overall very good.  The touchscreens do suffer from decreased responsiveness, presumably due to a more budgetary resistive touchscreen interface.  Air France, the carrier I took, offers software downloads via the usb charging port.  Its software is still buggy, as the recipe downloads link to nonexistent files.  Hardware amenities in business and first class cabins include additional footrests, extra reclining space, AC power, snakelight reading lamps, and a coat rack.

The lavatories are clearly more updated in design compared to old craft.  As with other modern craft, the faucet has motion sensors, and the lighting has softer modified fluorescent/halogen bulbs.

Travel on the Airbus A380 was an overall pleasant experience.  The amenities will certainly vary depending on carrier, but most of the airlines that have this equipment (Qantas, Singapore, AF…etc) all have decent in-flight services.  The appeal, however, lies in the double decker configuration.  There is something to be said about being able to walk a flight of stairs in mid-flight.

Several years ago, TSA implemented a checkpoint system for airport travelers, in hopes of streamlining the security lines. At LaGuardia, there are four lines:

1. Family Traveler
2. Casual Traveler
3. Expert Traveler
4. First Class

While each category of traveler is self-explanatory, I can’t fathom ever opting for the Family Traveler line (conceivably the slowest moving line of all). Of course, this line is intended to prevent single travelers stuck behind a family of screaming kids with strollers.

Interestingly enough, when I checked through security last week, the Family traveler line was clearly half the length of the “Expert Traveler” line. I took a gamble on the “Family Line” and breezed through security in about five minutes–it would have taken me at least 15 minutes to get through the “Expert Line”.

The next time I travel, I’m definitely going to take note of the “Family Line”.

I’ve been stuck at the airport gate for hours numerous times waiting for my delayed flight to be cleared for take-off. I see the flight agents typing away at their 1970′s-style computers frantically to rebook stranded travelers. Behind them sits an aging dot-matrix printer churning out airline codes on reams of paper.  Every so often, I hear a muted announcement over the loudspeakers regarding re-routed flights. The passengers, miserable at best, are on their smartphones frantically texting their travel status to friends and family. Some of them sit in clumps near the power outlets to refuel their power-craving gadgets. How could an airport possibly function in such chaos?

In aviation design, there is no room for chance. Every detail serves a purpose. For instance, the design of airport runways required efficiency to the finest detail. Chicago’s Midway Airport is a prime example. Considered the “busiest mile”, the airport roughly consists of a square mile of runways closely surrounded by local businesses. Its longest runway runs approximately 6000-ft, which limits the size of aircraft the airport can handle. A fully fueled Boeing 747 with maximum payload requires a minimum ground speed of 200-mph for a safe take-off, not considering incoming winds. Approximately 13000-ft of runway is needed to achieve this speed. Furthermore, airfields with limited land area implement displaced threshold airstrips.

The area of the runway marked with chevrons is the displaced threshold region. This region indicates that no aircraft is to land directly on that portion of the runway. The designation applies often when noise ordinances or structural buildings prevent a gradual aircraft descent onto the runway from a particular direction. In many cases, the displaced threshold section also offers less structural support than the opposite end of the runway; the ground on which an aircraft touches down must be able to withstand a greater pressure (force / area) than the rollout region.

How the hell does air travel function with airports working the way they do now? It is futile to seek out an explanation. Airports operate the same way our eye clinic does–despite all the mis-scheduled patients, missing charts, absent technicians; all the patients are remarkably cared for at the end of the day.

We all have our travel horror stories. Some of us have missed our flights due to weather or airplane mechanical issues. I’ve read accounts of getting stuck on the tarmack for over 5 hours, or getting rescheduled to a flight after the holiday season.

My travel plans were recently foiled by weather AND the airline industry. Several hours after I had checked into my flight online, I discovered that my flight was canceled. Not via phone or email, but via seatcounter.com. I initially intended to find out whether I could catch an earlier flight, but noticed that my flight was not listed. Subsequently, I verified the cancellation on my Continental Airlines account page.

Canceling a passenger’s flight without notifying them until several hours prior to departure isn’t exactly the most responsible approach. Some of us travel hours to reach an airport. Not everyone has ubiquitous internet access to check on flights. For my return flight, I checked the airline website right before leaving for the airport (I was fifteen minutes away). According to the website, my flight was “on time”. Twenty five minutes later, when I arrived at the departure gate, my flight was 4 hours delayed.

One way to avoid being stuck at the airport is to reschedule your flight prior to arriving at the airport, especially if you know that bad weather is approaching. Airlines have become more amenable to rescheduling trips prior to the delays, and typically waive the hefty rescheduling fees. If you’re not in a rush to reach your destination, you can also volunteer to take a later flight. I’ve seen a number of travelers volunteer their seats on overbooked flights in order to obtain a complementary travel voucher and even first class seats on a subsequent flight. With rising airfare costs, a free travel voucher in exchange for a flight 4 hours later seems quite reasonable.

Several days ago at the Delta terminal of LaGuardia Airport, I heard a familiar whirring of a machine that sounded like a continuous tear of  paper. As I glanced around the waiting area, I caught a glimpse of a cabinet underneath a kiosk where the sound of emanating from.

Indeed, the sound originated from a dot-matrix printer, happily churning out piles of connected paper with terminal-sized font.  I wondered why anyone would still be using technology from the 1970′s, but given that it’s the airline industry (airline tracking radar from 1970′s), I wasn’t too surprised.

But still, why not upgrade? The only other time I’ve seen a dot-matrix printer in operation is in the fire-alarm system of the research building.

I suppose that dot-matrix printing still has its merits. As long as the printer paper doesn’t jam, the system is virtually indestructible. A power source and a serial/parallel connector is all you need to print away. Sure, dot-matrix font is shitty, but the ink ribbon rarely needs to be replaced. Given that the fire alarm printer is locked behind a glass window, I doubt that it ever gets serviced either. Ultimately, I suppose that dot-matrix printers still have a niche: reliability with low maintenance and reliability over quality.

Still, I don’t see myself getting one of these devices anytime soon.
