I'm looking into best flights this September from HR to St Louis, stop there 3 days, then on to Phoenix, and then back to UK from San Francisco. Best flights for these destinations are United, and I realise I have to check to make sure they haven't altered any flights.
Never done this before so want to get it right and could do with your expertise.
One flight I like goes into Chicago terminal 5 and arrive 10 32am. Onward flight goes from Terminal 2 at 12 43.
My questions -
is this enough time to get bags, get to new terminal, ?
and what happens if first plane is late and I miss connection? Will they put me on next available plane at no extra cost?
Also I'm not registered for airmiles, is it worth doing for this journey?
Any advice please? Thanks
