A holidaymaker has shared his flight from hell after a fellow traveller allegedly drank 10 Bacardis and was sick over him.

He then had to stay in the vomit-soaked seat because the flight was full.

Bruce Mckenzie took to the British Airways Complaints Advice Facebook page to share his experience.

He wrote: 'On a recent 11-hour flight from Johannesburg to Heathrow, the BA flight staff served the passenger next to me 10 Bacardi mini bottles in the first few hours of the flight. 

'He became so intoxicated that he vomited on himself, the seats, the floor, myself and the passenger on the other side of him. 

'The flight was full, and we were unable to move anywhere. 

'An attempt was made to clean up the mess, but the whole experience was terrible and unacceptable, as the staff giving him this volume of alcohol was complicit in the vomiting.'

In response to his complaint,  Mr Mckenzie claims British Airways gave him a £50 voucher.

A screengrab of the response from British Airways reads: 'I'm very sorry to hear about the unacceptable experience you had on your flight from Johannesburg, caused by the behaviour of an intoxicated customer seated next to you.

'We fully understand how distressing and unpleasant it must have been for another customer to become unwell due to intoxication, resulting in vomit on your seat, clothing, and the cabin floor.

'This is certainly not the standard of experience we want any of our customers to have, and I'm sincerely sorry for the impact this had on your journey.

'We don't underestimate the importance of comfort, dignity, and a safe environment on board. While our cabin crew follow strict procedures regarding alcohol service and disruptive behaviour, there are occasions where situations escalate despite their best efforts.

'I can assure you that your feedback has made a difference. I've shared it with my colleagues in the relevant team, and we regularly use comments like these to guide us when we review our safety procedures.

'As a gesture of goodwill, we would like to offer you either 10,000 Avios or a £50.00 eVoucher, which can be used towards a future British Airways booking.

'Please let us know which option you would prefer, and we'll be happy to arrange this for you.

'Once again, please accept our apologies for your experience on this trip.'

Mr Mckenzie said he is 'openly disgusted by the response and the service'.

One commenter wrote: 'Absolutely shocking! I hope you told them what to do with it.'

'New fear unlocked,' and 'everything about this is absolutely disgusting,' wrote others.

The Daily Mail has contacted British Airways for further comment.
