The Most Extreme Airline Schedule Padding I’ve Ever Seen

It’s normal for airlines to pad their schedules significantly, and it’s a trend that’s becoming more and more common. One metric on which airlines are judged is their on-time record. The problem is that a flight being on-time often has little to do with it being operated efficiently. One way that many airlines have improved their on-time records is by simply padding their schedules.

I find this trend to be annoying, since you end up arriving at your destination “early,” and as a result there’s often no gate ready. This situation is entirely avoidable, and leads to a lot of time being wasted.

Last November, Danny Lee of the South China Morning Post wrote about how Hong Kong Airlines became the world’s most punctual airline. The airline operated about 95% of flights on-time in the previous month, which is a significant improvement compared to previous years, where their on-time record wasn’t nearly as good. As a vice-chairman of the airline was quoted as saying “we saw on-time performance (OTP) was a problem, so we allowed extra time.”

Anyway, it’s pretty normal to see airline schedules vary. For example, looking at flights between New York and Los Angeles, I see that block time for nonstop flights varies from 5hr55min to 6hr55min, based on the airline and time of day. I can sort of rationalize that.

However, while randomly looking at flights I noticed what might be the single most extreme block time variance I’ve seen on a given route. A flight from Beijing to Bangkok covers a distance of ~2,050 miles. I’d assume a flight like that would take a hair over four hours in the air.

Now, Beijing is notorious for horrible air traffic control delays, so I totally understand why these flights would often be delayed. So, how extreme are airline schedules in this market? Pulling up the schedule for tomorrow, I see Ural Airways has a nonstop flight blocked at 4hr10min, while China Eastern has a nonstop flight blocked at 6hr5min. That’s a difference of 1hr55min on a flight of ~2,050 miles, which is crazy.

In fairness I think Ural Airlines’ block time is way too short, while I think China Eastern’s block time is way too long. Most other airlines are in the 5hr to 5hr25min range, which seems more reasonable.

But a 6hr5min block time for a flight this short? I’ve never seen a flight blocked at that much time.

Does anyone know of a route where schedules between nonstop flights vary by more than 1hr55min?!

Just checked through https://flightaware.com/live/flight/CES2071/history/20180223/1100Z/ZBAA/VTBS This particular flight of China Eastern, the transit time is from 5h 9m (Feb 11th) to 6h 19m (Feb 19th), so, the block time at 6h 5m doesn't seem any inappropriate.

Also interesting is KIX-PVG (815mi, example date 13 May): MU 730 blocked at 2:05 MU 516 blocked at 3:15 HO 1338 blocked at 3:20

In terms of padding time vs flight time I find LGA-ORD the worst route actually - AA routinely blocks their shuttle flights at 2:56 flying time, which on a flight of 734mi is essentially double the actual flight time. Still - rarely arrive early!

I prefer extra time blocked for flights. Arriving early is way way way better than arriving late when it comes to connections or meetings in your destination city. Gates not being available on occasion seems to be a pretty minor problem in comparison.

Astana - Kiev. Airastana fly direct with 4h30min. Ukrainian air have 6h20min block. First time I flew this I was amazed when Ukrainian landed 2 hrs “ early”. I was quite confused wondering if I got time zones wrong or if we landed at the wrong airport. For such low volume airports I put it down to Ukrainian being a basket case.
