Arriving at Boise (BOI) FAQs
Cheapest Fare (ECONOMY) typically refers to the lowest-priced, non-refundable economy ticket with basic seat selection and limited or no checked baggage included. When arriving on a cheapest-economy ticket, expect more restrictive change and cancellation policies and possible extra fees for baggage and seat upgrades. Compare total trip cost including baggage and seat fees before booking to ensure it's truly the most economical option.
When traveling with a cheapest economy fare, plan ground transportation in advance to avoid last-minute expenses—book shuttle services, rideshares, or car rentals early for lower rates. Many low-cost itineraries arrive at major hub airports where public transit connects to city centers; research schedules and purchase tickets ahead of arrival. Factor transit time and baggage handling into your itinerary when choosing connecting flights.
In November, especially around Thanksgiving, airports and transit systems are busier and delays are more common; arriving on a cheapest economy ticket may limit your ability to change flights without fees. If you must arrive during holiday peaks, allow extra connection time and consider purchasing travel protection or flexible fare upgrades. Also check arrival airport hours and holiday transit schedules before booking.
Cheapest economy itineraries commonly arrive at major international and domestic hubs such as Los Angeles (LAX), Las Vegas (LAS), New York City (JFK/EWR), Chicago (ORD), Miami (MIA), and Atlanta (ATL). These hubs provide extensive onward connections and budget ground-transport options, making them ideal for low-cost arrival strategies. Use hubs to combine low fares with efficient connections to nearby destinations.
Cheapest economy arrival tickets often include only a personal item and charge extra for carry-on and checked baggage; seat selection may be limited or paid. Review the airline's basic economy policy for exact allowances and fees and consider adding baggage or seat options during booking if needed. Balance upfront ticket savings against potential add-on fees to determine total trip cost.
Travelers arriving on cheapest economy fares should prepare documents ahead of time, use expedited entry programs (Global Entry, Mobile Passport) when eligible, and check estimated wait times at arrival airports. During busy months like December, allow extra time, follow signage for primary inspection, and keep contact details and onward travel information handy. Consider choosing flights that land during off-peak hours for faster processing.
