I had an amazing day at the United Airlines Singapore office Regarding foreign COVID travel limits and documentation requirements, I got some inquiries. The agent printed out the most recent travel instructions for my trip in addition to providing clear answers to all of my questions. They even assisted in verifying my ESTA visa waiver for my trip to the United States. This type of assistance is crucial during a period when travel regulations may seem daunting. A big thank you to the crew for their knowledge and patience.
