Chief Commercial Officer and Executive Vice President at Southwest Airlines
Thanks, Tammy. I'll walk you through our second quarter revenue results, provide context for our third quarter outlook and update you on some of our commercial priorities. And for additional detail on our revenue performance, I'll point you to this morning's earnings release. Starting with second quarter. Demand continues to be resilient, especially for leisure travel.
Overall, trends have remained steady with operating revenue for the first half of 2023, consistently well above 2019 pre-pandemic levels. Operating revenue for second quarter was an all-time quarterly record of just over $7 billion. And in fact, we had record operating revenue in every month of the quarter. Second quarter 2023 unit revenue or RASM decreased 8.3% on a year-over-year basis on a capacity increase of 14.1%.
And while it's a year-over-year decline, it's still our second highest second quarter RASM to date, which points to the tough comp we were up against from last year. And as a reminder, year-over-year RASM was impacted by a five-point headwind from approximately $300 million of higher-than-normal breakage revenue that was recognized in the second quarter of 2022, resulting from flight credits issued during the pandemic that were set to expire prior to our later policy change to eliminate flight credit expiration dates.
Overall, second quarter revenue came in at the favorable end of our expectations as close-in leisure held strong. Second quarter revenue from corporate travel came in largely as expected, as we realized sequential and year-over-year improvement in managed business revenue. And while travelers from some of our largest segments have reduced their frequency of their business trips from pre-pandemic levels, we're very pleased with the gains we continue to make in the managed business space.
Small and medium businesses, government and educations are strong points for us, and we are growing the number of accounts we have under contract. All of this has allowed us to continue to grow our share of the managed business space in the industry and as a result of our revenue initiatives in corporate travel. We gained additional passenger market share in the second quarter and exited the quarter seeing more unique travelers flying for business than we saw pre-pandemic.
Moving to the third quarter, we're seeing leisure booking and yield strength continue throughout the summer travel season with July revenue, which is essentially booked expected to also be a record. Of course, much of the Post Labor Day booking curve comes in closer but we're very encouraged by the response to our June fare sale for off-peak fall travel and what that suggests for continued leisure demand.
We had all-time record bookings the week of our fare sale with three booking days that were top 10 all-time records and included our record day for the most bookings ever taken. In fact, we have more passengers booked for third quarter travel at this point in the curve than we did at the same point in time for second quarter. Of course, on a revenue basis, nominal yields are typically weaker sequentially third quarter versus second quarter but the strength in passengers points to the continued demand for Southwest Airlines. We currently expect overall corporate travel to have a modest underlying trend improvement, and we expect to continue our gains in industry market share.
Overall, however, we expect corporate travel demand will remain lower than leisure for the foreseeable future, particularly compared with pre-pandemic. So with a higher leisure mix, and as the number of business trips taken per traveler remain down for our most frequent customers, it gives us an opportunity to look at our current network design. Pre-pandemic, those travelers had a skew of short-haul travel with more frequent trips and also more midweek travel, and our current network is designed assuming those travel patterns would return.
Moving forward, there is a revenue opportunity to adjust the network to adapt to the new travel patterns we expect to continue to see from our mix of business and leisure customers. Ultimately, this leaves us with third quarter unit revenue expected to be down 3% to 7% year-over-year on capacity up roughly 12% again on a year-over-year basis. The decline in year-over-year unit revenue is driven by capacity growing faster than seasonably typical as we restore the network and normalize the utilization of our fleet as well as tough prior year comparisons from the post-pandemic domestic demand surge. So while there is still room to optimize our unit revenue efficiency, this guide implies a third quarter record for operating revenue.
So again, we are in the process of adjusting our network to support our imperative of industry-leading financial performance. Starting with the January 2024 schedules, we've made changes to the composition of the network such that it supports the customer travel behavior changes I just mentioned.
We made changes that reflect where our customers are traveling and when they're traveling, including time of day and day of week and this optimization will be largely complete in spring of 2024. In addition, we have more than 10% of our markets under development, which will normalize closer to pre-pandemic levels over the next 12 to 18 months. So as we said in the release and as Bob mentioned earlier, the go-forward revenue opportunity from the network is substantial.
And of course, we also expect continued revenue contribution growth from our existing and fully implemented revenue initiatives. Finally, we've always worked hard to consistently deliver the best hospitality and customer service here at Southwest. Our customer service is, of course, legendary, and our customer policies are industry-leading. And we are on track in deploying our onboard product initiatives, including WiFi upgrades, larger overhead bins and in-seat power.
We are now focused on widening our customer service advantage through prioritization of a series of initiatives that will improve our digital hospitality and allow our customers to serve themselves in most cases. We aren't ready to provide you all the details there, but the initiatives will help us achieve our goals to deliver the best and most efficient hospitality with next-generation tools, airport layouts and more.
And now with that, I'll turn it to Andrew.
