The Trump regime has made it difficult to travel to the US, as explained in Anthony Dennis’ article (Traveller, April 12). Yet in the next four years the US will be holding the two biggest sporting events in the world: the 2026 FIFA World Cup and the 2028 LA Olympics. How would any tourist, who has spent thousands of dollars to attend one or both events, feel if they were denied entry to the US and then deported? Perhaps for the World Cup, fans should buy tickets only for those matches played in the co-hosting nations of Canada and Mexico with the same type of boycott applying to the LA Olympics.Robert Pallister, Punchbowl, NSW Singing Singapore’s praises My daughter and her partner had been planning a six-week European trip for more than a year. All was booked and they were ready to go. A month before departure, my daughter was diagnosed with a serious medical condition with treatment needed as soon as possible. They had purchased an early-bird flight from Singapore Airlines, with limited options for changes. My daughter advised Singapore Airlines of her situation. A form was submitted. Within a week, the fare for her and her partner had been credited back to her credit card. Singapore Airlines, thank you.Charles Davey, Roseville, NSW
