Here is something to consider, Ryanair were taking deliver in 2017 of its first example of a 738 with short field performance, EI-FZX. I'd suggest these will be the vehicle of choice at SEN. Couldn't find details of how many examples in the fleet, but I heard 5 at DUB. I'd also suggest with capacity drying up in London, SEN will be big for Ryanair. A Dublin based 737 most unlikely to do SEN as there are no early morning take off slots available, certainly not pre 8am, so would be highly inefficient use of a frame .. details from internet on EI-FZX...
The 737 design enhancements allow operators to fly increased payload in and out of airports with runways less than 5,000 feet long.
The design enhancements include a two-position tail skid that enables reduced approach speeds, sealed leading-edge slats that provide increased lift during takeoff, and increased flight spoiler deflection on the ground that improves takeoff and landing performance.
The short-field performance changes were developed in 2004 in response to Brazilian airline GOL's needs at Santos Dumont airstrip in Rio de Janeiro. The 4,300-foot runway is short compared to other runways and could not accommodate larger aircraft at higher approach speeds with full payloads."
for those interested;
Short Runway Package Technical Aspects:
- A winglet lift credit, achieved through additional winglet testing, that allows the use of lower landing-approach speeds
- Takeoff performance improvements such as using sealed leading-edge slats on all takeoff flap positions, which allows the airplane to climb up and away more rapidly on shorter runways.
- A reduced idle thrust transition delay between approach- and ground-idle speeds, which improves stopping distances and increases field-length-limited landing weight.
- Increased flight-spoiler deflection from 30 degrees to 60 degrees, which aids brake performance when landing.
- A two-position tailskid at the rear of the aircraft. The tailskid protects longerbodied 737-800s against inadvertent tailstrikes during landing, which allows higher aircraft approach attitudes and lower landing speeds.
