3544quebec - the IAD-BOG flight is also AV-operated. DL just issued the ticket.

chuck1 - I have no first-hand experience, but know from others that AV will pay for a hotel if the misconnect was within their control. If it's a weather-related delay, for example, they don't pay for a hotel. This information relates to economy passengers, however, so I don't know if C gets a different and better treatment.
