Bologna, home to the infamous spaghetti dish is a reasonable small city, less visited than Milan or neighbouring Tuscan towns but nice in its own way. Somewhat surprisingly it has two airports geared towards low-budget flights. Bologna airport is no more than 6km from the centre.
Forli on the other hand, is not Bologna by any stretch of the imagination. If your flight arrives at Forli during the day, you will have no problem taking a bus to Forli train station where you'll find onwards travel to Bologna, it's also close to Rimini, the gateway to that luringly small country San Marino. Renting a car should also not be much of a problem and the motorway is just a stone's throw away.
Budget flights have the tendency however to land at the most inconvenient hours, such is the case with the flight from Warsaw that sees the rent-a-car shut , there's also limited onward travel that effectively means you're stranded in the small town. Forli, is not an awful destination but if it's a short trip you are taking, you'd probably rather be in Florence or Venice and it could be seen as a bit of waste of a night. What's more the town is rather devoid of cheap accommodation meaning you'll have to fork out 30-50 euros for a rather pokey room.
The airport itself is pretty much what you would expect from a distant airport servicing cheap flights. It has a tin shed feel to it and resembles a petrol station from the outside, driving through the airport is quite cramped, the interior is very basic with little more than a coffee stand and place selling sandwiches for amenities. The airport closes at midnight so do not plan on staying there during the night as you'll be ushered out.
WizzAir is the airport's main carrier along with a handful of other routes from Albania, Ukraine and Norway. This is not a fantastic airport but as long as you know what to expect, the savings made by flying to Forli can be well worth it.
