Construction works finally began in October 2010 and were expected to be completed before Euro 2012; however the deadline was not met and instead the airport began to operate in July 2012. A new 5 km rail spur branching off from the existing Warsaw–Gdynia line will be built with an underground station at the airport, theoretically providing a 30-minute commute to Warsaw centre. Although the first aircraft was meant to depart Modlin on 16 July 2012, the airport was officially inaugurated the day before, and the first passenger flight from Budapest arrived at the airport around 17:30. Low-cost-airlines Wizz Air and Ryanair started to use the airport as bases. On 22 December 2012 it was announced that the runway at the airport would be closed to larger aircraft such as the Boeing 737 and Airbus A320 indefinitely for safety reasons. Ryanair confirmed on the day of the runway closure it would divert all aircraft to Warsaw-Chopin Airport until the runway was repaired. Wizz Air also confirmed that it would route its flights to Chopin Airport until Modlin re-opened. The official re-opening took place over six months later on 4 July 2013 after construction works to fix the runway had been completed. On 17 July 2013, Wizz Air announced it would not return to Modlin despite its re-opening, but stay at Warsaw-Chopin Airport instead. Ryanair returned to Modlin on 30 September 2013 and since added more routes to its initial schedule. On 19 September 2013 the Category I Instrument Landing System was officially ready for use. At the same time tests began for the Category II Instrument Landing System which was ready for use by 1 May 2014. In October 2015, the airport welcomed its 5th millionth passenger overall.
