Tampa to San Francisco Nonstop for 2 Years!

ROUTE ANALYSIS: Tampa to San Francisco on United Hits Two Years of Service
May 18, 2019

For this edition of the Pelham Aviation blog I’ve decided to look back on the first two years of direct service from Tampa to San Francisco on United Airlines. The airline announced on July 25, 2016 that it would be starting a once daily service connecting the two cities on February 16, 2017. Prior to the direct-flight service kicking off, the airport reported that roughly 600 passengers traveled this route daily, albeit with a connection. According to the Tampa airport this was the largest unserved route in America. With the daily service having begun in February 2017, it recently surpassed two years of daily service by United Airlines. The passenger data reported by the USDOT indicates, to no surprise, that this route has been successful. In fact, United Airlines has announced that beginning on June 6, 2019 the route will be served twice daily, with an evening departure being added to the existing morning departure. So, let’s get into the T-100 air carrier data reported by the Bureau of Transportation Statistics.

The data for this investigation starts in February 2017 and extends through the end of 2018. The number of one-way departures during this time period reached nearly 700 on this daily scheduled flight. Almost 100,000 passengers flew from Tampa to San Francisco on this nonstop flight, showing an average load factor of 84.2%. This route also showed a decent amount of belly cargo (freight and mail) with over 567,000 pounds carried one way. The annual totals are shown below, with the seats and passengers rising year-over-year as 2017 was only served for 10 and a half months. Unfortunately, the average load factor dropped after the first year, but this could be due to larger aircraft being used, higher prices being charged by United, or lower prices being offered by competitors. Nonetheless, the load factor is something to monitor moving forward.

I also reviewed this route on a monthly basis to check the seasonality of the route and see if any trends could be identified. Excluding the inaugural month, the data showed that February of 2018 exhibited the lowest passenger total, seat total, and load factor. Only 4,400 seats were offered in the 28 days, and these were filled by only 3,140 passengers for a load factor of 71.2%. On the positive side, June of 2018 showed a load factor of 95.7%. Another notable discovery in the monthly investigation was that December of 2018 showed 43 departures, with a corresponding rise in seats and passengers. Even with the rise in departures and seats for this month, the load factor was still a respectable 78.6%. The summer months for this route performed well, while January, February, and September lagged.

The final piece of this investigation was into the aircraft type that United Airlines chose to fly for this route. The leading aircraft by number of seats was the B737-900, which had 233 one-way departures. The Boeing 737-800 was second in seats, but it was first by departures at 245. In third place was the A320 with 202 departures. In a distant fourth place was the A319 with only 16 departures. It will be interesting if this route will be served by smaller mainline aircraft (-800 or A319) since it will be served twice daily, though this is not reflected in the busy summer schedule. A check of random dates in June show one departure each on the -800 and -900.

It’s honestly quite amazing that this route was not served by a nonstop connection prior to February 2017. The nonstop flight shows a block of between 5.5 and 6 hours. Among the 1 stop options available are a Southwest flight through Phoenix (7 hours), a United flight through Denver (7 ¼ hours), an American flight through Dallas-Fort Worth (7 ¼ hours), a Delta flight through Atlanta (8 hours), and a Frontier flight through Denver (10 ½ hours and the cheapest option). As stated previously, this route has so far served 96,500 passengers from Tampa to San Francisco alone. The two-way passenger total is assumed here as double, for 193,000 passengers. The amount of time saved by these passengers is incredible. Assuming they all opted for the nonstop flight instead of the fastest 1 stop connection, a collective 289,000 hours was saved!

Moving forward, it would be interesting to see if a competitor to United steps forward. The ULCC carriers have a very minor presence at the 3 San Francisco area airports (SFO, SJC, OAK) so they aren’t being considered here. However, Southwest Airlines serves all three airports and already offers a flight to Florida from both San Jose and Oakland. With each already having a connection to Orlando, would Southwest be interested in adding a flight to nearby Tampa? Or, maybe farfetched, but would Southwest consider flipping one of the two San Francisco area flights from Orlando to Tampa?
