Peter's Notes:
Non-stop.
Late Summer/Fall/Winter travel. No min. stay. Fare can be bought one-way for half the lowest roundtrip price. No peak holiday travel at this price.
Travel between mid-August and early January.

When we checked, we found seats at this price departing SEP 13 and returning SEP 20. There are other dates available as well.

United sells basic economy fares on this route, which limit your carry-on allowance to just one small personal item such as a purse or small backpack up to 17x10x9 inches. Other restrictions apply. Consider the slightly higher regular economy fare if you need more carry-on allowance.

CheapAir charges a $15 booking fee.
To the best of our knowledge, there is a reasonable amount of seat availability at the stated price. Flexible travel dates may be required to find this rate; seats may not be available on all flights or all dates of travel. Holiday periods may be excluded. We monitor the availability of the fare and take efforts to remove and/or modify fares when no longer available.
All mandatory taxes/fees are included in the price. Tax-inclusive fare may be a few dollars higher or lower depending on the airport you connect through, if any. Baggage fees, if applicable, and other optional fees are not included. Our Dealhounds found this airfare using flexible date search. This means we searched a range of dates to find you the best price.
