I have relatives who spent 2 weeks in Iceland, at the right time of year, they never had a clear night to see lights...there is a lot of luck involved with the weather and solar activity, no app gets it 100% correct. I had one week and saw them twice...they were pretty good I thought but the guide called them "average"...you always want better.
On a trip to Northern Norway to see the lights I got a blizzard for the 3 days I was there, planes delayed, caught a cold, slipped on ice etc...should have stayed home. (UK at the time luckily not CNS)
If I luck out with the weather or something closed, I compare it to a tourist coming to CNS and getting 30 knot winds and rain on their reef trip. You are still disappointed but you gotta try.
Their cabin baggage allowance used a smaller bag than is accepted on any other airline that I've flown on, and while this was made clear on their website, it caused a major inconvenience having to check the bag in rather than take it on board or gate-valet it. One and only time I flew with flybe, and never again. If they hadn't been so miserable I wold have flown them more.
