Frequently Asked Questions
How early should I get to the airport for a domestic & international flight?
For domestic flights, we recommend arriving at the airport at least 2 hours before your scheduled departure time. For international flights, aim to be at the airport at least 3 hours prior to ensure smooth check-in, security checks, and to account for any unexpected delays. It’s better to be early and relaxed than rushing at the last minute right?
When is the best time to buy airline tickets?
Timing is everything when it comes to grabbing airline tickets. Typically, it’s best to book around 4-6 weeks in advance for domestic flights and 2-3 months for international routes. But the prices also depend on the travel demand, seasonality, and major events. You can always monitor the fare trends on Traveloka and set alerts to catch the best deals or promotions!
What is the cheapest day to fly to Houston?
Looking for the best deals to Houston? Historically, midweek flights (particularly on Tuesdays and Wednesdays), tend to be cheaper due to lower demand. However, airfares can fluctuate so we recommend keeping an eye on flight prices and being flexible with your travel dates. Booking in advance can be one the hacks to travel to Houston without breaking the bank!
What information do I need to know when booking a flight?
When booking a flight, every choice sets the tone for your trip. From the preferred flight route – be it direct or with layovers – to the in-flight experience – whether you opt for a standard economy seat or a luxurious first-class journey – and understanding baggage limits, there's a lot to weigh. Other considerations include travel insurance and the airline's booking policies.
How far in advance should I book an international flight?
For international flights, it’s wise to start your search about 5-6 months ahead with the optimal booking window being around 3-4 months before departure. This period often provides a balance between good fares and a reasonable choice of flight times and routes. But please note that several factors such as destination popularity, peak travel season, and regional major events can influence the timeline.
Do I need a passport and visa to fly between Seattle Tacoma Intl to Houston?
Traveling from Seattle Tacoma Intl to Houston typically requires specific documents. For international flights, a passport is almost always necessary. However, for domestic flights, neither a passport nor a visa is usually required, but an official ID will be needed.
