I was going to post this in the Wizzair section, but thought it was more suitable for here.
I recall the brazilian airline GOL took a short field version of the 73H. The press release talks about airfields less than 5000 feet, specifically an airfield in Rio at 4300 feet ~1300 meters. The press release is suitable vague on details, at one point suggesting "full payloads" but later that 2-4000lb increase could be expected. It would seem that the 73H could make it into and out of SEN - how far it could get I don't know. I know FR blocked ~30 seats at BHD when they started. BHD has a declared take-off length of 2299m for take-off. I think they later did sell at 189 seats, but flights were predominately to mainland UK airports.
