Hello.
I asked this question on big websites who sales air tickets but I never had an answer.
I would like to buy an economy air ticket from A to B with A Airline booking on Expedia (ie) with my AMEX GOLD credit card with no insurance.
Then I would like to buy an business air ticket from B to C with B Airline booking on Expedia (ie) with my AMEX GOLD credit card with no insurance.

Whats happens in case of such a delay from A Airline that you miss your connection with B airline ?

Thank you for your answer or your analyze.
