HI i recently travelled to america for five weeks with my patrner and four year old daughter. Our trip was for medical treatment and meant us flying to miami for four weeks and then travelling up to orlando for the fifth week and then flying home. We booked this through virgin holidays as we had never travelled with our daughter before who was disabled and we needed specialist assistance as she is unable to sit up she needed a travel chair with a five point harness which virgin provide. When we landed at the airport we where left to struggle with our bags and wheelchair onto a bus to be able to go and pick up our rental car we were not offered any assistance. For the whole five weeks we where out there we did not see or have contact from any rep. The main problem was when we went to fly home, we arrived at orlando airport and went to book onto the flight that was detailed on our travel itinary only to be told that we where not booked onto the flight and that we were booked onto a flight out of miami instead of orlando. we showed them the itinary we had been given and was advised there must have been a mix up but that there was no space on the plane and that we would need to fly the next day. We advised them that our daughter was disabled and that we only had 24 hours worth of milk and that she could only have a special formula which we had sent out from the uk and that her epilepsy medication was running put. (our daughter is fed by gastrostomy and can not take anything orally) we explained that this would effect the quantity of food she would have. WE also asked them to make sure the travel chair would be available as she would be unable to fly without it.we were given a hotel room but was told we would have to pay for our own food and drink and try and claim it back on our returmn. the next day we went to board the plane to find that it was not a virgin aircraft and as such had no seat for our daughter and extremely small amount of leg room as well as apalling food. We told the crew that we needed an adapted chairand was informed they didnt do them and thsat we would need to hold our daughter for the eigt hour flight or get off the plane. We tild them that if we didnt get home our daughter would starve as we had no more formula for her aor medication which would mean she would start fitting at which point we where told it was our decision. In the end we got her car seat brought up but it was too big for the seat and meant that she had no where to put her legs and they where up by her chest the whole flihgt. None the less she cried the whole flight where she was in such pain. I have wrote a letter of complaint and am waiting a response but wopild like some advice as towhat we can do when we get the response.I am sure that several safety rules must have been broken
