I'm not sure whether this is in the right place, but...
Anyway,
I'm looking at flights from the US to Leeds (where I'll likely be studying next year). So far, it looks like it'll be cheapest to fly into Heathrow and take a train up to Leeds. I found a flight that I really like on Icelandair that goes from Washington, DC to Reykjavik then has a 1 hour and 20 minute layover before going from Reykjavik to London. I'd have to change planes. There is another flight I could take that is the same route, but the layover is 9 hours.
Is 1.3 hours enough time to reach my connecting flight on time or would it be best to endure the longer layover?
Also, a few related questions:
Will I need to pick up my checked luggage and re-check it for my connecting flight?
How feasible is it to take suitcases on a train? I've never been on one, so I have no idea how that works.
