I'm currently in Finland, Rovaniemi. I started from Mauritius, took BritishAirways to the UK (have a return ticket) then took two Finnair flights to Helsinki then Rovaniemi (return tickets here too).
At passport control I was asked for my return flights and dates.
Now I want to avoid returning through the UK and instead take a train to Helsinki from Rovaniemi, then use another airline to return to Mauritius via UAE. This flight will take off in the evening, compared to the original return flight which should leave in the morning. Also I'm going via train for the first leg (Rovaniemi to Helsinki).
Is there any issue if I take this route and not follow the one I mentioned at passport control when entering the country?
