Reus airport is not widely known and so you will find flights to Reus are generally cheaper than to larger airports like Barcelona. There are also excellent transport connections from Reus to take you to Barcelona, Tarragona, several resorts on the Costa Dorada and Reus town itself.
To have the best chance of getting a cheap flight aim to book at least 2 months in advance of your trip.
