This was four months ago. I was taking my DDs aged 2 and 1 to Lanzarote, flying from Gatwick. All inclusive 2 weeker.
Flight left Gatwick 5 hours late. First 2 hours not really sure, general delays, but last 3 hours (when we were stuck on plane) were because no planes leaving or landing due to weather. Tbf when planes were allowed we were very quickly off.
Couldn't land in Lanzarote (too windy!), and so flew onto Gran Canaria! Arrived in a hotel there at 3am. Spent most of next day transferring back to Lanzarote.
Got to hotel in Lanzarote c6.30pm, about 22 hours after should have done. Holiday great afterwards. We did get free tea, meals on plane, etc, but nothing else was offered.
Ultimately, none of this was TUI's fault - all due to weather etc. But it was hard as I was in early stages of pregnancy and had sole responsibility for a 1 and 2 year old.
My understanding is there is no compensation as TUI did not do anything wrong themselves, and post Brexit/Covid that's now a requirement. Does anyone know? I'd be quite happy with vouchers btw as I'll be using them again!
