A report in http://www.lowcostportugal.net today and based on IATA slot allocation lists from the website of Portuguese Airport operator ana.pt states that Ryanair has made a request for over take/off 4000 slots at Lisbon Airport (Portela) for the IATA winter seasons between November and March 2014.
Ryanair pede slots para voar em Lisboa no Inverno 2013-2014
It is already late for announcing routes for this period. lowcostportugal.net posits that this may be a negotiating tactic on the part of Ryanair to bring pressure on the new owner of airports authority, ana.pt to reduce landing fees.
