A capital of villages
London is a vast, low-slung capital that grew by absorbing villages, so it reads as dozens of distinct neighborhoods rather than one grid. The Underground and a dense rail network make it a transit city at heart; in the center a car is a liability, discouraged by narrow streets and the congestion charge. The landmarks and business districts cluster in the middle, but much of London is the high streets and parks further out. It is large, so crossing town takes longer than the map suggests.
City access
Heathrow is the main airport, west of London and among the busiest in Europe. It has a fast dedicated rail link to the center and is also on the Underground, so reaching the city without a car is straightforward. Allow extra time at peak hours, both on the roads and through its large terminals.

Big, flat, and spread wide
Dallas-Fort Worth is two cities and a wide tangle of suburbs across the flat north Texas plain, with the airport set between them. It is one of the most car-dependent big metros in the country: the freeways are broad, the distances long, and transit thin outside the centers. Dallas leans corporate and polished while Fort Worth keeps more of its western character, and most of the region is the sprawl in between.

A closer look at the route, not just the seat
FlightSide now shows the two cities and key details about the flight alongside the seat recommendation: confirm you picked the right airports, read the time change off two clocks, and check the return leg.
It's all about the sun (after all)
