Travelport attributed the increase to growth in Travel Commerce Platform revenue. That was also the reason given for its 3% uptick in revenue in the fourth quarter, to $589 million.

The company's net income fell 46% in 2018, to $75 million. Travelport attributed that drop largely to a $72 million decrease in operating income and a $22 million increase in loss on early extinguishment of debt because of debt refinancing in March.

Travelport did not hold an earnings call Friday in light of its acquisition agreementwith Siris Capital Group and Evergreen Coast Capital Corp.
