Example Input: Article: London Heathrow is the biggest airport in the UK, and it also handles more international passenger traffic than any other airport in the world. For this reason, enlargement was planned and on 27th March a fifth terminal opened to help to deal with the many passengers that pass through the airport. The new terminal has taken a long time to plan and build. The idea was first proposed back in the 1980s. The opening of it has been talked about widely in the media in the UK and expectations were high for the PS4.3 billion project. However, in spite of long preparations at Terminal 5 ahead of the grand opening, things soon went into a mess. There were problems from the very beginning as staff had difficulties finding car parking spaces and getting through security to get into the building. This consequently caused a delay when passengers started to arrive and large numbers of staff were not in place. Long passenger queues formed and the slow start meant that everyone had to play catch-up from the beginning. Staffs were having problems using the new systems and a baggage operator told the BBC, it was all "shambles the moment the doors opened". The terminal has been designed to handle 12,000 bags an hour but due to a reported "lack of training and essential support that was promised", a backlog of luggage soon appeared. By lunchtime on that first day, 20 flights had been cancelled to try to alleviate the problems. Flights continued to be cancelled in the days following the opening and up to 28,000 bags have now had to be placed in temporary storage. The British Airline, the only airline operating at Terminal 5 says it is working to clear the backlog, but the negative publicity caused by the shambles has not helped the airport or the airline's reputation at all.
Answer: They had to wait a long time and play catch-up when checking in.
Example Output: What was the difficulty that passengers met with on the very first day of the opening?
