If you travel by train, you should buy a ticket to Coimbra. If you come by plane, you should buy a ticket to Lisbon or to Porto. The airport that is most convenient for intercontinental flights is Lisbon, although Porto is closer to Coimbra. Further, the airport in Porto is not very close to the Porto's railway station. If you arrive in Lisbon, you can either take a taxi or a bus to the Oriente Railway Station (Gare do Oriente). If you arrive in Porto, you should take a taxi to the Porto-Campanhã Railway Station. There are daily trains connecting the three cities (Lisbon-Coimbra-Porto). You can see the timetables of the fast trains (Intercidades and Alfa Pendular) Lisbon-Coimbra-Porto and Porto-Coimbra-Lisbon here. You can also consult the timetables of all trains (you may find Oriente Railway Station as 'Lisboa - Oriente').
In both cases you should exit in Coimbra-B railway station, where you can take a train connection to the Coimbra-A station in the city centre (this connection is included in the price of the ticket). Please consult the connections between Coimbra-B and Coimbra-A on October 4, 2015 in the train time results. On the left side of this Central station you can take a bus (no. 103) that runs via the University. There are also daily buses connecting the three cities (Lisbon-Coimbra-Porto). You can see the schedules of the buses in Rede Expressos. The bus stations are not located at the airports, so you will need to take either a taxi or a bus from the airport to the bus station.
