Nicholls then said they saw a young Italian man get turned away at the gate. "He looked really panicky, but he could only speak Italian so we couldn't find out what was wrong."
The mistake the young man, Nicholls and Doory had made? Thinking the test had to be valid for the arrival time, not the departure time.
According to Nicholls, they weren't the only ones who were confused and said other passengers had been given a 30-minute leeway but they were still 10 minutes over that time.
"To me, it's just not clear," she said. "We lost money for airport car parking, flights plus we had to purchase new flights, new Covid tests and new airport parking."
For easyJet, the rules are explicit and must be followed in order to operate in various destinations.
"Passengers travelling from the UK the Italian authorities require a negative Covid test result to have been taken within 48 hours of arrival which unfortunately the passengers didn't have," said an easyJet spokesperson
"Like all airlines, easyJet is required to comply with the requirements of the local authorities in all destinations where we operate."
This isn't the first time EasyJet has made headlines for turning away passengers with incorrectly timed Covid-19 tests.
In August the carrier refused a mother and son to board a flight bound for Croatia who similarly timed their tests for departure time, not the arrival.
The family took their required tests at 8.55 am on Monday, but would arrive two days later at 9.10 am UK time. Exceeding the 48-hour window by 15 minutes.
