Delta Air Lines is set to expand its European network in 2026 by introducing new routes to Malta, Olbia, and Porto. The airline's planned service to Olbia in Sardinia marks the first time the city will have direct North American flights, while Malta will see scheduled service from a North American operator for the first time. In Porto, Delta’s entry will bring two US airlines to the city, a development that may challenge TAP Air Portugal as it continues to grow its presence there.
This expansion reflects an ongoing trend of focusing on Southern Europe for both vacation travelers and those visiting friends and relatives. Next year, Delta is scheduled to serve more cities in this region than ever before. However, alongside these additions, Delta will discontinue all flights to London Gatwick and Geneva and reduce its Brussels service by half. Further changes are expected as schedules are finalized.
Based on data from Cirium Diio analyzed for July travel patterns from 2015 through 2026, Delta currently plans an average of 99 daily departures to Europe during July 2026—its highest yet for that month. The carrier expects to serve 28 European airports next July, which would be the largest number since at least nine years ago.
