When a 20% chance is absolutely painful – Alaska Air on-time statistics
Omar recently had yet another rant about Alaska Air.
People who don’t fly Alaska regularly don’t quite seem to grasp the severity of what this is such a problem. Delayed flight are normal right?
Well let’s run through a typical scenario: Earlier that day, you had woken up at 5am to fly to Redmond in time for a day full of meetings starting at 10am. 8 hours of meetings later, you leave main campus, fight Friday afternoon traffic and get to SeaTac – where the rental car return lot has moved yet again. You go through the masses of weekend leisure travelers and get to your gate. It’s been a long long day.
And then, you realize that your flight back to home sweet home has the following statistic:

Yes, that’s right. 20%. That means that your flight at 8:46pm has a 1 in 5 chance of pushing back on time.
What this really means is that your flight home has an 80% chance of being late.
Suddenly the odds don’t sound that good, do they?
Your flight will end up departing at 9, 9:20, 9:45, or 10pm. And you’ll get home at around 11:45, midnight, or 12:30.
What a way to end the week.
Now do you get it?

No I don’t get it. So many people have a life filled with way more hardship than yours. Stop whining and keep driving your BMW.

Rose and I know exactly what you’re talking about. This past Friday, she was on flight 324 SEA – SJC. It was delayed… 2 hours delayed. Actually, everything was delayed 1-2 hours.
I wish they’d give customers a little transparency on what’s going on. Is there bad weather? Did a flight crew just quit? Is it just impossible for the flight to be on time becuase of logistical reasons?
If a flight only has a 20% chance of being on time, you’d think that’s something that should be fixed ASAP…

The afternoon delays are typically a consequence of the cascade effect – delays are cumulative.

Hey sorry for being harsh earlier. I was in a similar, albeit different, situation with much greater consequences.
At any rate, here’s a guy that had a similar problem to you while on his way to Seattle.
