Tickets tickets tickets

I have been racking my brain where to fly into and where to fly out of. I have been using kayak.com because they allow you to sign up for daily email alerts. Since I am living in Korea I have been following the cost of flights from Seoul to Bangkok, Hanoi, and Phuket. I looked into the costs on a couple different days of the week. It tends to be cheaper flying Tuesday-Thursday and more expensive on Friday-Sunday etc. They are currently all about the same price mid-week and since Hanoi is looking like a better option for me I have also started watching Seoul to Hanoi the month prior to the date I want to fly to see if it changes so I can try to predict the trend.

I have been watching the prices for about a month now and they seem to be pretty stagnant only moving up or down a couple dollars here and there. I will follow for another month or so and make sure the dates work for me and that the tickets will not go down any further then I will purchase a one way ticket to Southeast Asia, mostly likely Hanoi. I have already gone ahead to make sure that this will not be a problem with visas and entering Vietnam. I will need to apply for a multi-entry visa and show proof of funds and possibly onward travel.

As for my return tickets I have also been watching ticket prices for December. I plan on traveling until about the 20th of December. I have found that that time of year the tickets are all the same from one day to the next, Sunday to Saturday but they differ depending where you fly out of and where you fly into. I am from Rhode Island so I have been looking at flying into Boston, my usual destination and Providence which is more accessible.

I am currently checking tickets for departure out of Bangkok, Vientiane and Hanoi into both Boston and Providence and found that Hanoi is the cheapest home, surprisingly. I was also happily surprised that the ticket price is the same to fly into Boston and Providence from Hanoi which benefits me because Providence is definitely easier. When comparing Boston to Providence I also am taking into consideration the length of the trip, if its more than 4 hours longer to fly into Providence it is actually more time efficient for me to just go to Boston anyways.

It's important to take into consideration the length of time from airport time, layovers and flight time to arrival. You may think you are getting a good deal and a cheaper ticket but sometimes if you look at the flight time there could be anywhere from 1 hour to 24 hours difference, which many times is not worth the slightly cheaper price. Also look at the departure times. Cheaper tickets many times have very difficult departure times, make sure it is safe and possible to get to the airport at the time you are looking to fly out.

Things to consider:
One-way tickets (visa issues)
Return tickets
Prices
Flight times
Different airport options
Different days of the week
