Thank you both so much for taking the time out to answer and help. I was able to ignore that section of Eva Air and am now checked in, thankfully! I will see what happens at the airport regards them asking for proof of onward travel. And, yes, sorry I was in a panic last night and posted the wrong dates! I fly in 17 October and leave 14 Jan, so 89 days, I believe! 💙
and Greg - that's super helpful and reassuring advice. I did make a mistake posting my dates and will be in the country for 89 days - I was aware of that before booking. I was able to check in by ignoring the visa part as you recommended, despite there being an asterix indicating it wasn't to be skipped. I will now look into onward flights as insurance, but do you think I could wing getting this up until getting to Heathrow airport and seeing if it's an issue with Eva Air? Am I likely to be challenged by Thai immigration on onward travel documentation/plans or is it just something that happens with the airline before outbound flights to Thailand? Many thanks to you guys again 💙
