If you consider the following then actually BOH is doing better than in 2007:
PIK - not exactly an essential route
DUB - not BOH's strong point, leave it to SOU with their high frequency
PAD - this was always gonna be a non-starter (!)
AMS - not BOH's strong-point, leave it to SOU with their high frequency
PSA - can think of far more popular Italian routes (FCO, VCE, VRN)
PRG - this route has suffered declines from a lot of the UK, not just BOH
VLC - probably would work if it was done by Ryanair versus TUI
Total lost pax from Aug'07 38,000
Suddenly that 85,000 in Aug'17 doesn't look so bad. With the above we would be looking at + 124,000.
BOH would be very strong if it focused on mid to long-haul and more Spain - if Palma carried 19,000 pax in Aug;17 that is seriously significant; they could support additional daily year-round services. Wizz needs to come back too considering the success of the Krakow service.
