American Airlines has round-trip flights from San Antonio (SAT) to Boston (BOS) for $159-$169 with a connection. Flights September to April. Weekends available.

American allows one carry-on bag and one personal item for free. You can avoid paying for seat selection by accepting the randomly assigned seat at the gate.

If you use the Citi® / AAdvantage® Platinum Select® World Elite Mastercard® with AA flights, you get: a 25% inflight food and beverage discount, a $125 AA flight discount after you spend $20,000 or more in purchases during your card year, and your first checked bag is free on domestic American Airlines flights for you and up to four companions traveling on the same reservation.

You can usually save more money by booking your flight+hotel together as a package instead of separately.

Do a search on Tripadvisor to find guides, tours, restaurants, attractions, and cool things to do. It’s a good resource to use for planning your day-to-day itinerary while on vacation.

  • Tips: Rent a car for cheaper by using Priceline’s “Express Deals”. The rental car company will be hidden until after you purchase, but this allows those companies to undercut the published rate indirectly. You can remove low quality companies from those hidden results. The trick is to use the quality filter on their website to remove any rental car company with a review rating under 7.0 and then pick the deals that survive the filter. Note that the quality filter is only available on the desktop/web version of the Priceline website and isn’t available on the mobile version.
  • Tips: Use Tripadvisor to create a Hotel “short list”. First, plug in your dates and destination. Then select “Sort by Traveler Ranked”. Finally, select the “Traveler Ranking” filter to show “only 4* and up”. Use this resulting “short list” of hotels to find the cheapest one with a high ranking.
  • Tips: Hotel rates for Weekend dates are usually higher than the rates for Sunday through Thursday. Tripadvisor has a color-coded date calendar, red when the average hotel price for that day is more expensive, green for less expensive. You can use this to get an overview of what dates in the month are at a discount.
  • Tips: Different booking websites will often have differing routes, prices, and availability. Before you finalize your purchase, do a quick check on BookingBuddy, Skyscanner, and Kayak to see if any other site or airline is offering a better deal.
