Andrew's Notes:
Non-stop.
Travel through early November. No min. stay. Fare can be bought one-way for half the lowest roundtrip price.
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.
