Whenever I've flown to the US, so far always used an airline based over here in the UK. This time I've booked Delta - OK it's not a direct flight to Orlando but our family have saved about $1000 flying via Atlanta. What I've heard so far from people I know who have travelled with them is that they are very good. Just wondered how they compare to other US airlines and any others that you've used - as far as being on time, comfort, service etc. - oh and the food of course and if they do kids meals. Is Atlanta airport easy to find your way around? Perhaps you would also know how far ahead you can prebook seats?
