Sabre has recorded almost $1 billion in revenue for the second quarter in a row, giving it $1.97 billion for the first six months of 2018.
The travel technology company's half-year revenue is up 8.6% compared to the same period in 2017, with second quarter takings up 9.3%.
Adjusted EBITDA for the first half of 2018 climbed by 3.5% to $578 million.
The profit figures are a turnaround on the same time last year when the company had flat adjusted EBITDA growth compared to the first six months of 2016.
The company's overall revenue metric is also performing better than at the middle point of 2017, with two percentage gains against quarterly and half-yearly figures for that period.

President and CEO Sean Menke says the wider "macro global travel environment" is helping support the growth.
Sabre is forecasting a full-year revenue target in the range of $3.76 billion to $3.94 billion.
The final two quarters for adjusted EBITDA are likely to be lower than those recorded for Q2, as the overall full-year growth rate is still expected to be in the region on 0% to 3%.
In the distribution wing of the business, Sabre increased revenue by 10.9% in the first six months of 2018 compared to the previous year.
Hospitality technology is up 8.1% over the same period, and its airline counterpart is up 2%, with the latter showing a fall of 2.4% to $204.8 million in Q2 of 2018.
The number of airline passengers boarded via the Sabre-hosted platform fell by 10.2% to 370 million in the first six months of this year, in part due to the loss of Southwest Airlines as a customer.
