Why did my Canon 550D save only JPEGs for part of a trip after I set RAW+JPEG?

I set my Canon 550D to record RAW+JPEG before a trip and did not intentionally change that setting. After importing into Lightroom, I found that some images from the middle of the trip were JPEG only, while earlier and later photos had both RAW and JPEG files.
What could cause this on a 550D? Can shooting mode changes or accidental button presses switch the camera away from RAW+JPEG without me noticing?

If I'm going to be honest here, I think the most likely explanation for this is that you did in fact (accidentally) change the quality setting - an slight squeeze of the Q button plus a jog of the control wheel is all it takes.

Yes—there are a couple of likely explanations.
The most likely is that the image quality setting was changed accidentally. On the 550D, it does not take much to alter quality settings through the controls, so it’s possible to switch from RAW+JPEG to JPEG-only without noticing.
Another possibility is shooting mode. If you switched into a fully automatic mode during part of the trip, the camera may have recorded only JPEGs, then resumed RAW+JPEG when you returned to P/Av/Tv/M.
If you are certain the setting never changed, and you have not reused the memory card, you could try file recovery software in case the RAW files were deleted or became inaccessible.
So the practical explanation is usually either an accidental quality-setting change or a temporary switch into an auto mode that does not save RAW files.
