Delta Air Lines has announced massive expansion plans for the summer 2025 season. In particular, the carriers latest move includes additional transatlantic capacity, with new routes connecting American cities to Catania, Naples, Rome, and Milan in Italy, Barcelona (Spain), Dublin (Ireland), and Brussels (Belgium). Clearly, Delta Air Lines focus points to Italy for next summers expansion. It is also worth noting that Delta says summer 2025 will be its biggest-ever transatlantic summer. The same period this year was Delta’s busiest European summer ever.
