MV, Very useful figures. Lets hope the airlines are using these.
As a backup guide as to who was operating over the past few years
2004 - Monarch (A330-200) / XL (747-300)
2005 - Monarch (A330-200) / XL (747-300)
2006 - Monarch (A330-200) / XL (747-300) / TOM (767-300)
2007 - TOM (767-300) / XL (747-300)
2008 - Monarch (A330-200) / XL (A330-200)
2006 cleary the busiest year for the route, and as i stated further down, this was the year when some flights were only going 80-90% full, namely the TOM flight who were the newest carrier on the route. Airtours have a big following and so do Travel City. Also XLA have cut capacity in July/Aug by about 200 seats per week now they use the Airbus instead of the old 747's.
However they now operate one flight in may and one flight in october over the school holidays.
2007 improved for TOM as TCX/MYT no longer chartered Monarch to operate for them and used the Thomson aircraft instead.
Judging by these figures there is more than enough demand to support one weekly flight from both CWL and BRS.
There is a lot of leakage to London, Manchester and Birmingham from Wales for long haul routes, especially long haul charter.
