Made an international flight booking for a Garuda Indonesia flight on Expedia. Fairly normal name with one word First, one word Middle, one word Last. Specified easily enough as Expedia has a text box for each.

Took an hour or so to ticket and expedia emails look normal. However using 'My trip' on Garuda airline it shows as Firstnamemiddlename Lastname, e.g. if my name was John Middle Smith, it shows as Johnmiddle smith

Is this still okay? I found some old threads but even Garuda web interface seems to say this isn't the correct way - unfortunately box is grayed out on their portal.

I don't want to confuse some newbie agent and end up worse off, but equally does worry me a bit.
