I am planing a vacation in Orlando FL, in Oct flying from LHR, and have been checking around for some good flight deals.
One particular site I visited offered cheap flights with UA via IAD, both on the outward and return legs. The only problem I can foresee is that the outward connection is 1hr and 15mins and the return is 50mins. I don't see this as viable, what do you think?. If I did take these flights and missed the outward connection due to immigration or some other reason outside the airlines control, would they still be obliged to put us on the next available flight, or could we end up having to buy a new ticket?.
