Cheers for clearing that one up for us SASFox.
As you mentioned the Malaga service is to be operated by the scheduled Jet2.com Sunday morning service while the based TCX, Airbus 320 goes down to Monastir instead now as you quite rightly mentioned.
The Monday Reus service only runs for about 6 weeks during the summer school holidays in August and September. By all accounts its a load share with a Glasgow based TCX, Boeing 757-200, operating GLA-LBA-REU-LBA-GLA.
