Enter Air has added a 26th Boeing 737-800 to its fleet as it expands capacity for the busy summer season and beyond.

The aircraft, registered SP-ESQ, is the 38th plane in the airline’s colours. It was formally delivered on 26 May and entered service on 30 May.

The new arrival is the last of two used Boeing 737-800 aircraft that joined Enter Air’s fleet this year.

The airline said the extra jet will increase its transport capacity during the summer peak and in the months outside the high season. Enter Air did not provide further details about routes or planned deployment.

The addition reflects a continued reliance on the Boeing 737-800, a model widely used by European leisure carriers because of its range and seating capacity. For airlines that operate charter and holiday services, such aircraft help match demand when passenger numbers rise sharply in the warmer months.

Enter Air has been steadily building its fleet in recent years as demand for package travel and charter flights has recovered. The latest delivery gives the carrier more flexibility at a time when operators face pressure to balance higher seasonal demand with aircraft availability and operating costs.

Fleet growth can also matter outside the peak summer period. Extra aircraft allow airlines to adjust schedules, support contracts with tour operators and respond to changes in demand without stretching existing resources.

Enter Air is one of the largest charter airlines in Poland and serves leisure markets across Europe and beyond. Its fleet mix is central to its business model, which depends on efficient aircraft use across a relatively short operating season.

The addition of SP-ESQ brings the airline’s total fleet to 26 Boeing 737-800 aircraft, with the newly delivered plane now available for regular operations.
