Sample flights

All routes included with these discounted fares are nonstop flights to and from Boston. Flight times and date availability, as well as the fares themselves, are subject to change.

Boston to Chicago on United

The discounted United fares between Boston and Chicago are for its bare-bones basic economy class tickets. This fare class charges extra for carry-on bags, seat assignments and checked bags. The basic economy tickets also do not allow flight changes or upgrades.

But if you are a MileagePlus Premier member, have Star Alliance Gold status or booked the fare with an applicable MileagePlus credit card, you can bring a free carry-on bag on board and check a free bag even on basic economy. Otherwise, expect to pay an extra $60 for the trip, or you’ll have to travel carrying just a personal item.

The sample flight listed here is between Boston and Chicago in the first week of November. Many of the discounted fares are for Tuesday-to-Tuesday itineraries like this one, but other date choices are also currently possible.

According to Google Flights, the $158 fare listed here is an amazing $258 cheaper than usual flights on the route. That’s a savings of more than 60%. Peak fares and holiday travel on this route can top $850.

Currently, you can still find reasonable flight times with these fares without resorting to red-eye or early-morning flights.

Tickets for this fare begin on selected dates in September and run through March 2023.

This fare is for United’s basic economy class, so again, unless you have mileage status or book the fare with a United credit card, you’ll have to travel only with a personal item or pay approximately $60 extra for the ticket.

Even if you have to pay the additional fare, this pricing is still a good deal — and a great one if you can take advantage of your status for the baggage allowance.

Boston to San Francisco on American Airlines

American Airlines, with codeshare partner JetBlue, is also offering some highly discounted flights from Boston. One of its best fares is $258 for a nonstop cross-country flight between Boston and San Francisco.

Like the United fare above, these prices are for a basic seat class that does not include carry-on bags.

GOOGLE.COM/FLIGHTS

As shown in the Google Flights search results above, you can currently find round-trip tickets between Boston and San Francisco for just $258. This fare represents more than $200 per ticket savings versus typical fares.

The shared flight between JetBlue and American Airlines offers two booking and price options. The JetBlue fare is for its Basic Blue economy seat class, which does not allow carry-on bags on board. You’ll have to make do with just a personal item that can fit under the seat in front of you. If you want to bring a bag, surcharges of at least $60 for the round trip will apply to your ticket.

The American Airlines fare for this route is $318, which is still close to $150 cheaper than average. The American fare is for regular economy seating, allowing carry-on bags. The price is equivalent to booking the ticket via JetBlue with its baggage surcharge. If you have American or JetBlue status or book with one of their credit cards, you may be able to benefit from a free luggage allowance.

If you can travel luggage-free or can score a free luggage allowance, this is a great fare to fly cross-country.

Don’t forget to use a card that earns bonus points on airfare purchases. Airline cards can always be a good call for earning status and rewards specific to those airlines, like for these flights by using the Chase United℠ Explorer Card or the Citi® AAdvantage® Executive World Elite Mastercard®.

For more flexibility with earned points, The Platinum Card® from American Express earns 5 points per dollar spent on airfare booked directly with the airline or through American Express Travel, on up to $500,000 of these purchases per calendar year.

The Citi Premier® Card and the Chase Sapphire Reserve earn 3 points per dollar spent on airfare, while the American Express® Gold Card earns 3 points per dollar spent on airfare when booked directly with the airline or through Amex Travel. The Chase Sapphire Preferred Card earns 2 points per dollar spent on travel.

Bottom line

Multiple airlines, including United and American, are offering discounted flights from Boston from this fall through the early spring of 2023.

Round-trip tickets between Boston and Chicago for $158 and between Boston and San Francisco for $258 represent great savings on regularly priced flights. But when booking these fares, be careful to note your luggage allowance, as most basic economy seats do not allow for carry-on bags without paying a surcharge.

If you can make the luggage allowance work for you (perhaps by leveraging airline status), these fares become great deals. If you find an itinerary that works for you, book the tickets quickly, as prices may change at any time.
