Syed paid for the tweet via Twitter’s new self-service ad platform. The story was picked up by social media website Mashable and word spread fast.

However, according to the BBC, it took four hours for British Airways to get the message and reply. The company said: “Sorry for the delay in responding, our twitter feed is open 09:00-17:00 GMT. Please DM [direct message] your baggage ref and we’ll look into this.”

“We would like to apologise to the customer for the inconvenience caused. We have been in contact with the customer and the bag is due to be delivered today,” said BA, according to the BBC.
