Have to agree with everyone else unfortunately. For whatever reason she is flagged on the system here and that’s an end to it.
The thing is as people are saying she was trying to play clever and get around the system and let’s be honest that’s not right, regardless of how many people do it doesn’t make it right so you’re kind of between a rock and a hard place I’m afraid
If you’re leaving from bkk they don’t but depends where you go to for example KL absolutely do weigh and make you check it in. However it is the most stupid system ever in KL as they weigh it on the scale as you go through and both myself and my colleague were over so we literally in front of them opened the small cases and put things like shoes back on instead of flip flops and our suit jackets on over T-shirt and shorts and I also rammed another shoe into my laptop bag she then weighed the case again and it was under so went through then literally put everything back in, an absolute joke but they just want you to check it in and pay more .. And if you’re concerned then just take more and check it in like everyone else
