The best time to book flight tickets is typically 2-3 months in advance for domestic flights and 5-6 months in advance for international flights. Prices tend to be lower during the middle of the week, especially on Tuesdays and Wednesdays.

You can change or cancel your flight ticket by contacting the airline directly or through the platform you used to book the ticket. Be aware that there may be fees associated with changes or cancellations, which vary by airline and fare type.

Baggage allowances vary by airline and ticket class. Generally, economy class passengers are allowed one carry-on bag and one checked bag, but it’s essential to check your airline’s specific policy for weight and size limits.

For domestic flights, a government-issued photo ID is usually required. For international flights, a valid passport and, in some cases, a visa or other travel documents are necessary. Check the requirements of your destination country before traveling.

You can check in for your flight online through the airline’s website or app, at a self-service kiosk at the airport, or at the airline’s check-in counter. After checking in, you can obtain your boarding pass electronically or as a printed document.

If your flight is delayed or canceled, contact the airline immediately to understand your options, which may include rebooking on the next available flight or receiving a refund or travel voucher. Airlines may also provide compensation or accommodations, depending on the situation and regulations.

You can request an upgrade when booking your ticket, during check-in, or at the gate. Upgrades can be paid for with cash, frequent flyer miles, or through bid-based upgrade programs offered by some airlines. Availability and costs vary, so it’s best to inquire directly with the airline.
