Artificial intelligence (AI) is being applied in multiple industries all around the world, and in travel, the technology has made big strides.We travel to Spain to find out how the airline Iberia and the hotel chain Iberostar are using AI to change the way they operate.At Iberostar, AI applications can analyse and predict the amount of food that restaurants will need, and hopefully reduce food waste as a result.Meanwhile, Iberia is using the tool as a personal assistant to help high-end travellers plan their trips.And we hear about some of the limitations of the technology if it's not applied properly.(Picture: Business woman with an open suitcase, preparing for a trip, while looking at her phone.
