I have noticed over the last couple of Wednesday's a couple of extra Thomson Flights .....
2352 / 2353 from Manchester to Fuerteventura
4342 / 4343 from Gatwick to Paphos.
Neither of these appear on the timetable on the Thomson Website, and both appear to use their flight number as their call sign (when I think flights to these destinations usually use the alpha numeric callsigns)
Are these flghts being operated on behalf of another Tour Operator ?
Both those flights are bookable on the First Choice website.
