I will be receiving flight benefits for a major airline starting in January, meaning I fly for free standby on any flight globally. I know some destinations like Thailand are very affordable and US dollars stretch further there. I’ve heard so often Thailand is a place where you can have a beautiful beach or city vacation for way less than you’d pay in many places, and the flight is what makes it prohibitively expensive. What are destinations that are comparable? Climate and continent don’t matter — interested in unique cultural experiences, natural beauty, and luxury for less than it would cost in the US. I love art, wine, food culture (from street food to fine dining), hiking, beaches, museums, historic places, music, etc. I'm open to traveling via public transit or otherwise affordable transport options once I'm off the plane (ie if there's some secretly cheap region of French wine country, I'm there). Also open to flying into one country to easily access another (ie fly to Finland, take a ferry to Estonia). I am a native English speaker and can get by with Spanish, but not perfectly. French is on my bucket list. Destinations I would have access to include:

A: Antigua and Barbuda, Argentina, Aruba, Australia

B: Bahamas, Barbados, Belgium, Belize, Bermuda, Bonaire, Brazil

C: Canada, Cayman Islands, Chile, China, Colombia, Costa Rica, Curaçao (they fly to Cuba too but I’m not sure what the current travel policy is from the US)

D: Denmark, Dominican Republic

E: Ecuador, El Salvador

F: France, French Polynesia (Tahiti)

G: Germany, Ghana, Greece, Guatemala

H: Honduras

I: Iceland, Ireland, Italy

J: Jamaica, Japan

M: Mexico

N: Netherlands, New Zealand, Nigeria

P: Panama, Peru, Philippines, Portugal

S: Saint Kitts and Nevis, Saint Lucia, Sint Maarten, South Africa, South Korea, Spain, Sweden, Switzerland

T: Taiwan, Thailand, Turkey, Turks and Caicos

U: UAE, United Kingdom (England and Scotland)
