I do have 3 airlines. I have tried at AA.com and also Orbitz but can never get the ITA itinerary to come up. Most of the listings are taken up by darn BA, that I don't want.
One problem is that neither site lets you specify airlines for individual flights. At Orbitz I can specify 3 airlines, but only for the entire trip, and they never come up with the ITA itinerary I have.
That's why I thought, should I not be able to email this to some agency and let them do it. I mean it is potentially big business, somebody must have thought of it?
