Many of us will be headed over the river and through the woods to grandmother’s house this Thanksgiving. Unfortunately a lot of us will have to brave the lines, delays and flu-infected crowds at the airport to get there.

To help make your Thanksgiving travel plans a little bit less daunting, Christmas decor retailer Treetopia has released its top ten of the best and worst airports for Turkey Day travel. The bad news is that all three Bay Area airports have cracked the top ten list of badness. Researchers crunched the numbers on 2018 government data on all the departing flights at the nation’s busiest airports to create this ranking. The bad news is that all three Bay Area airports have cracked the top ten list of badness. Making it to the big feast on time may be no mean feat.

“Our research team has looked into the issues surrounding Bay Area airports during the 2018 Thanksgiving Holiday and found that while SFO has a history of construction projects at the airport falling behind schedule and causing significant delays and cancellations, the primary cause of delays in the specific time frame around last Thanksgiving can be attributed to the Camp Fire in Northern California. Before it was contained, the fire sent smoke to the Bay Area in late November, causing poor visibility which impacted both arriving and departing flights.”

Oakland has the dubious distinction of being the fifth worst airport in the country with almost half, 45 percent, of its flight delayed. The average delay is about 11 minutes. San Francisco Airport, which ranked #8 has longer delays, running about 20 minutes, but only 41 percent of flights delayed. That’s the same percentage as in San Jose (#9) and the delays usually run about 15 minutes.

Some of this tardiness, the report suggests, is a lack of proper infrastructure to accamodate the huge number of passengers that fly through Bay Area airports.

“The Bay Area isn’t structurally prepared for the volume of people who pass through the airports to Silicon Valley and San Francisco. Construction and repair projects frequently take longer than the time allotted, especially when there is bad weather in play.”
