This is really minor, but shouldn't happen. I have an itinerary RDU-JFK-PRG and BUD-CDG-ATL-RDU. A few days ago I got a message on Delta.com that there was a schedule change. The only thing (I thought) had changed was the flight number on ATL-RDU.

However, when I went to look at the flight today, I noticed the BUD-CDG segment was missing on Delta, but it was still there on Air France (code share).

Should I be at all concerned about this, or will it show up again at some point? I have asked my TA to check it out.
