My girlfriend is from Peru and has been 83 days in France since July. She is coming in December until February where we will both leave the Schengen area. We planned to leave Europe for a few days (using http://www.schengen-calculator.com, it says she needs to leave for 11 days) but the cheapest tickets are 1 or 2 days after the date she has to leave.
Is it a big deal to leave after 92 days? Is there any other solution?
