A family was banned from boarding their flight after British Airways staff became suspicious of insect bites on their baby's leg, according to a report from SWNS.Expat Jonathan Arthur, 34, and his wife Xun Sun, 35, were flying from Shanghai Pudong Airport to London Heathrow for a family wedding.They noticed some insect bites on their 1-year-old son Josephs leg as they approached the boarding gate and asked airline staff where they could buy some allergy medication, just in case.FLESH-EATING NEW WORLD SCREWWORM COULD POSE HEALTH RISKS TO CATTLE, HUMANSWhen the staff at the boarding gate saw the bites and heard the family talking about allergy medication, they became concerned, the report stated."They asked loads of questions after they saw the bites, and so we told them about his mild peanut allergy," said Jonathan Arthur. "The medical staff at the airport said to apply some ointment and wait 10 minutes, which we were happy to do. But the BA staff said we needed to call their medical advice line. They thought his peanut allergy was the cause so they didnt want to take the risk."The family also sent photos to an online doctor, who confirmed they were insect bites but recommended administering some antihistamines to help with the swelling.The baby's bites were no larger than 1 cm in diameter and disappeared within 10 to 15 minutes after applying the bite cream, causing him no further discomfort, as stated by SWNS.PREGNANT WOMAN AND BABY SAVED AFTER DOCTORS FIND GRAPEFRUIT-SIZED TUMOR: 'EXTREMELY RARE'"It was nothing more than swollen bites," said Jonathan Arthur.Despite the fact that the baby's bites were already starting to subside, the airline said the family wouldnt be allowed to board without a "fit to fly" letter from a doctor.The Arthurs were escorted away from the gate, "feeling like criminals," according to the SWNS report. They rebooked with another airline that did not require a medical letter.CLICK HERE TO SIGN UP FOR OUR HEALTH NEWSLETTER"We were treated like we had done something wrong," said Jonathan Arthur, per the SWNS report.In a statement to Fox News Digital, British Airways stated, "We take the safety and well-being of our customers very seriously and do everything we can to support them when issues like this arise.
