Interesting codeshare schedule discrepancies
 

I was just checking the MA flight numbers for some MA-operated KL-coded flights in the next few days. I noticed that my return BUD-AMS flight is scheduled to leave and arrive 30 minutes earlier, as well as the operating equipment as a F70 instead of a 736. I checked the KL site and the timetable is showing the same. However, the KLM.com My Booking function is still showing the old schedule as is Amadeus (Checkmytrip). The NWA.com site (where the booking was made) shows the accurate schedule.

If one cuts it close and doesn't check, that's a good way to miss a flight.

This is an often recurring problem. The operating airline is adjusting its schedules or other operational characteristics yet fails to inform its code share partners of the changes or the codeshare partner fails to swiftly implement the changes, hence the discrepancies. Given the increasing number of codeshare partners on all flights, this problem is likely to worsen in the future.

At least KL gets the day of the week right. CO can't seem to do that

The schedule for Amtrak trains is offset by two days (CO thinks Amtrak's Sat-Sun trains run on Thurs-Fri).

NW is usually pretty good with schedule change updates (I get too many of them), pretty hard to argue here IMO.
