We departed from Luton Airport on 13th June 2018. We were originally supposed to fly with Easy Jet, but they saw fit to cancel their flights and LoveHolidays arranged for us to then fly with Wizzair. (We paid for Easy Jet 3x 23kg luggage), to our slight dismay we discovered that our luggage allowance (although transferred over) was then reduced by 9kg ( over 3kg per bag), however we had a total of four bags all under the weight of the combined 60kg, baggage allowance also includes dependant of size 10kg each hand luggage. I repeat we were well under the allowance, we had no problem checking luggage in, including my Dad's wheelchair, nobody in Luton questioned that we checked in four bags (despite the boarding passes showing three bags paid for). The flight out was delayed, amusingly we called to check in desk and boarding began, even though the plane was still taxing down the runway. May Mum and Dad were deposited at gate 20 for wheelchair assistance, due to the flight delay they spent approximately 45 mins, getting very cold waiting to be able to board plane. A lot of people paid for Priority boarding, although we didn't, we were quite amused that they were stood outside in the cold whilst us mere mortals waited in the slight warmth, for the plane to be emptied of its passengers and luggage etc. Once boarding commenced, my husband and I boarded in our pre-organised seats as per travelling with a disabled person. We were in row 29a to c. As the plane painfully filled up, I was approached several times and asked if I was travelling alone, this was because my Mum and Dad were sat in the disabled transport outside the plane for minimum of 15mins. They were eventually permitted to get on the plane, their hand luggage was placed halfway down the plane, as oversized hand luggage were permitted taking up room above the nearby overhead hold. We took off and our holiday finally began. Now the return journey: We again check in our luggage, not as smoothly run as in England, explaining that yes will need help getting on the plane but not requiring aide to get through to departures. The check in staff member then queried how many bags we checked in, and despite again being well under the 60kg, excluding the 40kg combined hand luggage we were permitted and also elected to have one of the hand luggage to go in the hold, we were informed that we would have to pay 65 Euro's for the fourth bag, as the weight is irrelevant and we had only paid for three bags. To say we were disgusted is an understatement. Please explain how in England common sense ruled and there was no issue but we were held to ransom in Bulgaria? Fuel is measured on weight not how many bags, an absolute slur to the end of our holiday. Hence we require a full refund. To add insult to injury, once we were seated (and this time we were all permitted to go on together and was first on the plane, row 29a to c), we were informed that Wizzair policy is that the disabled person has to sit next to the window (wasn't explained on trip out), not that it mattered as my Dad more than happy to sit by the window, however a strange policy all the same. Then as you will see photo evidence, my fold down table was broken, it had two orange stickers trying to hold it up - which was useless and not fit for purpose (the hostess said that should it keep falling down to let her know, I replied it keeps doing it and that was while we were still on the ground) - What a major safety failure- compare this to the trip out where we had continual turbulence so couldn't have table down/drinks stopped/unable to go to the toilet. But it is ok for useless stickers pretend to keep a table up, why should I have to keep holding it for three hours odd? should we of experienced the same severe turbulence, whom would be failing in safety of their passengers because their equipment is not fit for purpose. More amusing still, my Mum whom was in 29b, her table would not sit flat when pulled down, so she was unable to rest her cup of coffee on it, however not a problem to use mine as it helpfully was unable to stay up. So to reiterate we expect a full refund, we were well within our luggage allowance so should not of been charged for having two smaller bags because it made four.
