Tips for making a connecting flight

Unless your flying is confined entirely to trips from one big airport to another, you will likely encounter the need to connect from one flight to another. This "hub and spoke" model that most big airlines practice is based on the premise that they will serve all but their busiest city-pair markets with connecting flights.
Connecting flights allow one-stop service from almost anywhere to almost anywhere else, but that process also puts you at risk of missing your connection. And while you can never completely eliminate that risk, you can at least minimize it. Here's how.
Take a hike: Airports with the longest walks between gates
Know the minimum connection time required at your airport
Each airline sets standard minimum connecting times at each hub it serves. With any connecting flights you book as a single itinerary, through either an airline's website or a travel agency, the airline's system automatically adjusts for minimum times at your connecting point. If you miss your ongoing flight, the airline is obligated to put you on the next available flight with no additional charges.
Most airlines post their own connecting times on their websites. Some of those minimum connecting times are incredibly short for a big airport, as low as 30 minutes in some cases, and usually less than 60 minutes for domestic-to-domestic connections. International times are usually more than an hour, and can exceed two hours at airports with separate international and domestic terminals. Some airlines add even more time for connections involving jumbo jets.
But individual airlines' postings typically do not show connecting times for connections between different airlines. The International Air Transport Association (IATA) compiles extensive minimum connecting time data, but does not offer this information to the public. The Global Distribution Systems (GDS) that travel agents use show connecting times, and the OAG (Official Airline Guide) and Skyguide also publish connecting time information, but only to subscribers.
If you don't use a travel agent or subscribe to something, you're out of luck. I've been unable to find any comprehensive online listing of IATA connecting times that doesn't require payment. And, in any event, airlines often post minimum times that are shorter than IATA times.
Fly on a single ticket when you need to connect flights
Typically, any connecting itinerary you arrange on a single ticket conforms with whatever connecting times apply. That's true even on tickets that involve two airlines, as long as those airlines have interline agreements. The booking systems automatically incorporate requisite times. And single tickets usually provide for checking baggage through from origin to destination, including interline transfers.
But I recently heard from a traveler who ran into a problem, even with a single ticket. A ground agent refused to check her bag through from Europe to the U.S., claiming that her airline checked through baggage only when it connected to another airline in the same alliance. As far as I know, this is a rare event, a result of poor training rather than bad customer policy.
Stick to one airline or alliance on a connection
Where possible, book connecting flights on a single airline or on airlines that are partners in an alliance. Typically, at big hub airports, airlines try to make sure that their gates and partner gates are close together. If not, they provide inside-security people-movers or shuttles to any gates they use.
Even with a valid interline ticket, however, connecting at some big hub airports involves leaving security at one terminal and re-entering at another. And, at a few airports, a single airline may use two different terminals. Airlines should build time necessary to connect through separate terminals into the itinerary.
Avoid two-ticket trips when connecting flights
If at all possible, avoid an itinerary consisting of two separate tickets on separate airlines. Minimum connecting times apply only to itineraries on through-tickets. If you're on two separate tickets, your first flight is delayed, and you miss a connection, the second airline treats you as a no-show; it can cancel your reservation and make you buy a new ticket for its next flight. Sometimes, you can argue your way onto a later flight without penalty, but that's not a guarantee.
If you check baggage on a two-ticket itinerary, you almost always have to check it just to the connecting point on the first airline, exit security, claim it, haul it to the second airline's counter, re-check it, and re-process through security. Obviously, you need to allow a lot of extra time for that process.
Occasionally, separate tickets can be on the same airline. For example, if you buy a ticket to a nearby gateway to connect to a frequent-flier award trip. Here, whether or not you can check yourself and your baggage straight through to your destination is a crapshoot: Some agents will accommodate you, and some won't.
Pad your schedule
As noted, if you're on a single ticket and miss a connection, the airlines involved are on the hook to put you on the next available flight. But putting you on the next flight — providing, that is, if a seat is available — is not always a satisfactory solution.
Getting off a plane and walking to a distant departure gate can easily squeeze a 30-minute connection close to zero. That's why many travelers deliberately pad their schedules by scheduling a longer layover than minimum at a connecting hub. Airlines usually allow you four hours or more maximum connecting time. An extended layover is easy if your airline runs a lot of flights on both legs of the trip. But if the only feasible itinerary involves a close connection, you face white-knuckle time.
Allow lots of extra time whenever you're on a two-ticket trip. I always allow at least three hours. Four is even better.
Avoid the last connection
One of the world's oldest travel "tips" remains as valid as when it was first pronounced, probably more than 60 years ago: Avoid booking the last flight of the day out of your connecting airport. The reason is obvious. Yes, the airline has to put you on its next flight, but if your original connecting flight is the last of the day, the next flight will obviously require an overnight stay at the connecting hub and arrival a day late.
A corollary, based on the same principle, is to book a connection as early in the day as practical. Clearly, the more "next available" flights, the better your chance of arriving on the day you planned.
Pick the right hub for your connection
Often you have a choice of hubs, and you can avoid some white-knuckle hours by avoiding the hubs that are most prone to delays. According to current data, the worst big U.S. hubs for delays are Chicago O'Hare, Dallas/Fort Worth, New York JFK, Newark and San Francisco. The sunbelt hubs generally do better.
Unless you're on a single airline, avoid U.S. hub airports with separate terminals that lack inside-security or "airside" people movers. The worst airports for this are Boston, Chicago O'Hare, Los Angeles and New York JFK.
In Europe, London Heathrow crops up on almost everyone's "avoid if at all possible" hub airport lists, along with Paris De Gaulle and Frankfurt. Travelers generally prefer Amsterdam (Sky Team) and Munich (Star Alliance), along with such secondary hubs as Brussels, Copenhagen, Helsinki, Madrid, Rome and Zurich.
Come up with a baggage plan for your connecting flight
There is no one-size-fits-all "right" way to deal with baggage on connecting flights. Checked baggage can miss a tight connection or even go astray for a few days, but dragging a carry-on bag from one end of a huge terminal to another, even a carry-on bag with wheels, can slow you down and tire you. Decide for yourself which approach fits you better.
Where you sit on the plane matters when you have a tight connection
With a tight connection, try to get a seat toward the front of the cabin on your first flight. Even if you have to pay, being near the exit door can shave 5-10 minutes off your deplaning time.
Download one or more apps that can help you with the connection process by tracking delays and posting up-to-date information on departure gates: GateGuru can steer you to the right gate, Weatherbug will help you check on weather at your connecting hub, and AirportMaps shows you where you can grab a quick bite to eat as you're passing through the terminal.
And if you're worried you might have to spend the night at a connecting airport, HotelTonight could help you locate a bed. You'll probably also want your airline's app, too.
Direct flights are still the best option
A non-stop or direct flight is still the best way to avoid connection problems. Figure that a connecting itinerary adds a minimum of two hours to total trip time, and more likely three, so driving up to 200 miles to/from a different airport to catch a nonstop is often a good idea. As has been noted many times, the best way to deal with O'Hare is at 30,000 feet above it.
