I recently had a conversation on the other forum partly about whether Cardiff could sustain 2 carriers on Vuelings routes especially if that carrier was Ryanair. The replies weren't that positive about the possibilty! So i decided to have a look at the amount of weekly flights CWL used to sustain on 3 routes PMI, ALC and AGP for all carriers and compare it to what is on sale for 2018. I picked the first week of August in 2009 when the airport had started it's decline i numbers and the passenger numbers for the year was 1.6 million which the airport should get close to again in 2018. In 2009 the aircraft used were a mix of 733s, 738s, 757s and A321s. In 2018 it will be a mix of A320s and 738s.
PMI 2009 13 weekly 2018 12 weekly -1 weekly flight
AGP 2009 12 weekly 2018 7 weekly -5 weekly flights
ALC 2009 10 weekly 2018 7 weekly -3 weekly flights
So there could be potential for another airline to co inhabit on those routes whether in the future it be Ryanair, Norwegian or Jet2.
I also noticed that routes like Murcia, Girona, Sharm el Sheikh, Malta and Fuerteventura were also served. With TCX and TUI looking at Turkey and Egypt again then possibly CWL could get Bodrum and Sharm el Sheikh back in the future.
Jerry, I know you picked on 2009 because of the 1.6 mppa which CWL may well get close to in 2018. However, 2009 was a particularly bad year for CWL when it lost over 350,000 annual passengers compared with 2008 (its second best ever year after 2007). 2009 to 2010 lost another 325,000 but after that the losses lessened each year until the recovery began.
I've looked at the annual passenger numbers for 2009 and 2008 for the routes you mentioned and compared them with 2016.
Palma - 169,000 in 2008; 110,000 in 2009; 109,000 in 2016
Malaga - 139,000; 116,000; 83,000
Alicante - 151,000; 109,000; 93,000
Murcia - 31,000; 22,000; nil
Girona - 8,000; 6,000; nil
Sharm - 22,000; 25000; nil
Malta - 8,000; 7,000; nil
Fuerteventura - 19,000; 21,000; 1,500
So looking at 2008 there is clearly scope for significant increases on a number of routes if the dynamics are roughly the same as then.
