  • Tips: The Chase Sapphire Preferred® Card allows for 1-to-1 point transfers to several airline loyalty programs. Booking with points is a good alternative to paying with cash when the price of airfare is high. Here is the current list of Chase Sapphire transfer partners: United, Southwest, jetBlue, British Airways, Iberia, Singapore Airlines, Emirates, Air France, KLM, Virgin Atlantic, Aer Lingus, and Air Canada.
  • 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.
