Responding to the above.
TOM will go for SFB & CUN from BRS for logical reasons that have been well explained on many forums, many times.
Secondly, TCX flights for Summer 2017 will be once again operated by an A320 of Smartlynx.
Summer 2017 however may be a promising time for Vueling to take things up another gear. Flew CWL-BCN-CWL last week, flight well into 90-95%+ and there is a real buzz about CWL at the moment. The improved duty free area directly after security is now a nice fresh touch, with a new Cafe Ritazza opening adjacent to the Echo Bar sometime this/next week. Onboard there were numerous inbound Spaniards and others alike, with some passengers seemingly using BCN to connect to further VY destinations, encouraging signs.
Just another VY point to note, all of my experiences with them have been great, and I believe the onboard service and OTP of VY is superior to the UK Lo-Co's, not naming names ... CWL has a real gem in VY, and they are going from strength to strength with an additional 40% capacity for this Summer alone, coupled with the fact that PMI is now 4x weekly throughout the whole season until October.
