United Airlines (UAL) announces its trans-Atlantic schedule for next summer.

The Chicago-based carrier said it will fly to 37 cities in Europe, Africa, the Middle East and India, as well as returning service to several destinations including Newark and Stockholm.

The airline is offering 10% more trans-Atlantic service next year than it did this year and 30% more than it did in 2019.

Despite rising demand and increased revenue due to fare hikes, airlines such as United had a bumpy summer. Supply chain issues and staffing shortages caused many airlines to cancel flights or curb capacity.

"Airlines are being forced to reduce the flying because of passenger caps," said Patrick Quayle, ​​United's senior vice president of global network planning and alliances. "And so I would truly be speculating -- I hope it doesn't last longer than the fall and into the winter season. I hope it's resolved by next spring or next summer, but I don't know."

Global uncertainty, along with inflation, will still cast a shadow over travel in 2023. London Heathrow, Europe's busiest airport, recently said the "demand outlook remains uncertain," in an assessment of the industry.

The expanded schedule United is offering in 2023 is massive, with routes between San Fransico and Rome to Shannon, Ireland from Chicago O'Hare International Airport. An overall increase in daily flights is expected, culminating in 23 daily flights to London Heathrow next summer.

Delta Airlines (DAL), one of United's main competitors, will also be expanding its service to Europe next year, planning to grow trans-Atlantic travel by 8% from 2022.
