Bangkok Airlines Customer Service Issues

I urgently need help with switching a flight. Can we cancel one leg of a reserved flight and keep the connecting one? The passenger was supposed to fly from Bangkok to Chiang Rai (PG235) on December 16 and back from Chiang Rai to Bangkok (SL [redacted]) on December 17, and then from Bangkok to Khon Kaen (SL [redacted]) on December 17 as well. However, due to illness, she needs to stay in Bangkok. Can she keep the SL [redacted] flight and not travel on PG235 and SL533? We request permission for her to board SL645 from Bangkok without flying on the other flights. No refund is needed; we just need to change the initial boarding city to Bangkok instead of Chiang Rai. Please contact me to discuss this further and make any necessary rebookings. Thank you for your prompt response. Lisa, USA

Hello, I would appreciate some help with a flight reservation. The booking is for my daughter, Feline Esmee Holleman (May 29, [redacted]), with flights as follows: - Chiang Mai to Koh Samui on July 22, [redacted], at 3:10 PM - Koh Samui to Bangkok International on July 28, [redacted], at 9:15 AM She is listed as Feline Holleman, but her full name is Feline ESMEE Holleman. Could you please update the reservation to include her second name to prevent any issues during boarding? I am eagerly awaiting your response. Thank you for your help. Best regards, Mark Holleman
