I think those contributing to ths thread should be mindful of what they say with regard to the condition of the LS fleet. Using language like dilapidated and clapped out etc. Could get you into hot water. Jet2 have an impeccable safety record. Their aircraft are certified as air worthy too.
There are plenty of airlines out there with aircraft of the same age and older.
On a more general note it would seem like a logical step in terms of LS's differentiated strategy that they add medium and long haul holiday destinations for Jet2 Holidays. Hence, I expect that an announcement is about procuring an aircraft type for that. They are not many options.
Considering a wider perspective are their other carriers that they could collaborate with or could gain synergies by working closely with? Just a thought.
