Practical tips
Don't lose days on the road. At this distance, flying is the realistic option and keeps your itinerary intact. Book early on a reputable platform to get the best fare and an instant e-ticket.
Houston has two major airports, George Bush Intercontinental (IAH) and William P. Hobby (HOU). Look at the airport code on your booking before paying, so you head to the right one and plan your transfer accordingly.
San Diego International Airport has Terminal 1 and Terminal 2. Your airline determines which one you need, so check your confirmation email the day before and follow the signs once you arrive.
Budget fares often include only a small personal item. Compare the cost of a checked bag before booking, since adding it at the airport usually costs more than adding it online in advance.
Houston's airports are far from downtown, so decide how you will get into the city before landing. Rideshare, taxi and public transport options exist, and late arrivals may limit your choices, so don't leave it to chance.
The journey experience
San Diego to Houston is a long haul across the Southwest, roughly 1,300 miles as the crow flies. If you are wondering whether to go by bus, train or plane, the answer here is simple: the plane is the only sensible choice for most independent travellers. Overland routes would eat several days of your trip and the savings would not justify it.
Flying gives you a single, straightforward leg with a direct service available on this route. You leave from San Diego International Airport, which sits very close to downtown, and you land in Houston at one of its two main airports. Major US carriers serve this corridor, and the cabin experience is the same comfortable, no-fuss standard you would expect on any domestic flight. Checked bags and seat selection often cost extra on budget fares, so check the fare rules before you pay.
Our advice: book the flight, then plan the ground part carefully. Check which Houston airport your ticket lands at, because the two are far apart from each other and from downtown. Arrive at San Diego airport with enough margin for security, and look up your onward transfer before you land. With that sorted, this is one of the easiest long legs of a US trip.
