They like to cut the corners off cancelled or expired passports the send it back to you, should maybe tell them you've found it and ask them what to do with it.

Yer I have all my old passports, cancelled and expired,

I wish I'd kept every boarding pass in my life, I have no idea how many flights I've taken and where I've been.

Yer it's not a big problem but it can cause unnecessary hassle. The plane should tell you before you disembark, but they don't!

You must keep and show your boarding pass at the immigration desk, I've seen people have problems with this in the past.

At the priority immigration I'm never asked for it though, they are pretty easy going there.

Thanks guys, thought I'd ask I know if the Tuesday is a holiday they might try to swerve the Monday off too!!

Ok, thanks for the advice guys. I just checked my schedule and I'll be in the country for less than 60 days anyway, so worst ways my visa will be void and I'll only get a 30 day visa waiver (this is a bit annoying for me because I'll have to get an extension, but worse still get my tm30 stamped when I arrive, ready for the extension)

I should be (but not 💯%) using the business class immigration desks at Suvanabhumi (yes, this exists), and I always assume they are more lax there, although that's purely assumption, as I've never had ant real issues in over 30 entries to Thailand, touch wood, so I couldn't really differentiate between a strict and lax immigration experience.

Anyway, I'm just going to chance it, and incase anyone is interested I'll post a comment on this thread when I've passed immigration in a few weeks.

Thanks guys,

It is abit rubbish. I've had countless single, double and triple (when they were around) tourist visas over the years and never had this problem I even just checked my application form (I'd taken a photo of it) to double check it wasn't my mistake.

Thanks, that's good to hear. It's an easy mistake to make I suppose.

It won't hurt to ask them I suppose, just to be sure,
