United Airlines flew the most customers for a second quarter in its history, carrying 44.4 million passengers in April, May and June.
The US carrier also set a record for the most ever customers carried in a day by the airline at 565,000.
Its capacity was up 8.3% compared to the second quarter of 2023, according to the airline’s Q2 results.
Total Q2 operating revenue was $15 billion, up 5.7% year on year, with net income of $1.3 billion, compared to $1 billion a year ago.
The results noted that the United app continues to be the most downloaded airline app with more than 89% of customers engaging digitally on their day of travel.
The airline also launched a new seat preference feature that automatically re-seats customers when their preferred seat becomes available.
More than 30% of customers who have saved their seat preferences are moved to their preferred seat.

The airline also introduced limited-edition Wrexham AFC-themed amenity kits and pyjamas in premium cabins on selected long-haul international flights.
Scott Kirby, United Airlines chief executive, said: “At United, we have been effectively managing costs, cash and capacity against a challenging industry backdrop because we’re focused on doing what’s necessary to hit our financial targets.
“Thank you to leaders across the company for embracing a ‘no excuses’ approach to running our business.”
The airline also sees mid-August as an inflection point for domestic capacity for the US market, with published schedule changes showing an approximately three-point decline in industry capacity growth rate.
Kirby added: “The revenue diversity advantages that we’ve built with our premium customers, Basic Economy customers, and domestic road warriors, on top of the world’s best loyalty programme and leading customer service, have propelled our margins to near the top of the industry.
“Looking forward, we see multiple airlines have begun to cancel loss-making capacity, and we expect leading unit revenue performance among our largest peers in the second half of the third quarter.
“United has long been preparing for the moment when industry-wide domestic capacity would adjust – it’s now clear that inflection point is just 30 days away.”
