That seems plausible EI-BUD, in which case it would probably be more representative to take a rough average of the outbound and return flights to get an idea of where the fares are at, or just look at the return prices.
On a separate note I do find it a little disappointing that Thomson have just copied and pasted this years schedule for S16. It does surprise me that with consistently high loads and fairly high prices compared to LGW for flights/packages that Thomson have not tried to extend their offering from BOH at all. Incidentally EXT seems to have a quite a few flights operated by other airlines on behalf of Thomson for S16.
