Issues right from booking, pre booked seats changed twice by airline but charged us twice, booked in online got to airport changed seats again and we were separate and no extra legroom, manager refused to discuss. Flight was on the dirtiest , coldest airplane ever experienced and we flown plenty , even staff said it was such an old plane and always cold. Accommodation was poor not 4 star and nothing like the photos on jet2 site, the photos they used must have been several years old- unrecognisable. But the worst issue was the horrific stomach churning smell from sewage especially bad on the rooms . The smell got worse from the evening onwards and would wake us up, made us physically sick. Jet2 did nothing to help or keep us updated and have admitted they were aware of the issue pre arrival. Food and service very poor for what was not a cheap family holiday. Flight back great but then realised that both of our cases had been damaged, Jet2 agreed it was their responsibility but still waiting for a repair or replacement and have had to borrow some for our next holiday, expensive brand new cases! Over 12 weeks sine we have registered our complaint with full photos by email and recorded letter still no resolution just automated messages. Except things can go wrong and we have been very accommodating to all issues experienced but now out of patience the customer service is an absolute joke and we have not seen any evidence of their so called award winning service. The worst we have experienced in 40 years of travelling, makes us more determined to ensure we get fully compensated the more they stall and will pursue.
