It depends, if the head winds are strong enough even a wingletted 733 will
struggle. The rest is rubbish ofcourse, Jet2 operates 738's and 752's from other
UK airports to the Canaries without problems, but they can't operate them from
Blackpool because of the short runway, it's as simple as that and that's where
the problem lies.

Oh but they can. Jet2 have used a 737-800 Lanzarote to BLK. Also LS used a 737-800 from BLK Gerona.
BLK can handle 757s.
take-off
I had a nightmare Tenerife - MAN - Over five and a half hours. I used Jet2 BLK/Dalaman last year - No refuelling and the 737-300 made good time.
As for the length of the runway - 757 is the largest a/c that can operate from BLK - They need to get that land and lengthen the runway.
It was no shorter than SEN and wider - SEN managed until the runway was lengthened - BLK still has the wider runway, and that matters also.
