Flying from Baltimore to Austin: what you need to know
The flight
At 1,340 miles, this is a long domestic flight — about 3h 13m gate to gate on a nonstop. It deserves a bit of planning: eat before you board or buy early (popular items sell out), and pick your seat with the flight length in mind.
Airlines on this route
Southwest Airlines flies this route nonstop. That matters more than it sounds: the cheapest fare on one carrier is rarely the same product as the cheapest on another. Checked-bag fees, free seat selection and change rules all differ, so compare the full trip cost before you pick a winner. See our airline guides for exactly what each carrier charges — then send an enquiry and we'll confirm the all-in price for your dates.
Leaving from Baltimore (BWI)
Plan to be at the airport two hours before a domestic departure — ninety minutes can work at smaller airports outside peak times, but security lines are the one variable you can't control. If you're checking a bag, add time rather than cutting it close. Our Baltimore airport guide covers terminals, parking and ground transport so you can plan the trip to the airport, not just the flight.
Arriving in Austin (AUS)
Before you land, know how you're getting from the airport to where you're staying — it's the part of the trip people forget to plan. The Austin airport guide lays out your ground options, from transit and shuttles to rideshares and rental cars. Flying back the other way? Check Austin to Baltimore fares — prices on the return direction often move on a different rhythm.
When to book
For a trip of 1,340 miles, booking 3–6 weeks ahead typically lands you in the sweet spot. Leave it to the final two weeks and prices usually climb as the cheapest seats sell out. If your dates are flexible, midweek departures are where the lower fares hide on most domestic routes.
Good to know before you go
- If you're traveling with only a carry-on, you can skip the bag-drop line entirely with mobile check-in.
- Download the airline's app before you fly; gate changes and delays show up there first.
- Nonstop time on this route is about 3h 13m — a one-stop itinerary needs to be a lot cheaper to be worth the extra hours.

- Screenshot your fare before you enquire — prices move, and a saved fare helps our team match or beat it.
