I apologize if I'm posting in the wrong forum or thread, but I'm not sure where else to post and have an important question.

I've regularly used ITA for the last couple of years, but beginning this week, I started receiving a new error message stating that all of the "Departing from" (a/k/a origin) airports must be located in the same country. For example, if I insert CDG as my initial "Departing from" airport and then click "Nearby" and choose all airports within 2000 miles (including those from other countries), I will receive an error message when I run the search. If I remove all of the airports other than those located in France, the search will then complete without any problem. This is something new. I never had this problem before. I can still include airports from multiple countries in the "Destination" airport, but not the "Departing from." Does anyone know whether something has changed?
