Yes Excel normally use the 737-800 on this route with 189y config.
Its normally allways full so if you wanna try and get decent seats or at least seats together check in early or maybe ring there pre-fly dept to see if they can do something.
The entertainment normally consists of a main movie followed by a series of short programmes.I think the short prog have changed this summer and im not totally sure what they have.
Normally have a comedy,sitcom and a music video (abbamania and an audience with the bee gees last year).
Headsets were priced at £3.00 and yours to keep but if you have your own...the crew dont mind you using them.
Food is very tasty and of good quality,staff are friendly and helpfull and good choice from the bar.
For the way back i suggest that you bring your own blanket or something.
They carry about 20 blankets andthe pax are like vultures...everyone wants them.There nice and warm and fleecy.
