Great report!
I flew to ALC last week too with Jet2 (but from MAN) and got 75s G-LSAD (hybrid livery) and G-LSAE. I was very impressed with Jet2 like you were, they have done a good job with the interior, nice and airy feel to it.
Intresting to read that your inbound flight was bumpy, my outbound was choppy all the way through the day after your flight (23rd), high clouds.
Thanks for the report!
