Self-transfer and separate-ticket warning

Cheap mix-and-match fares can require entering the transfer country, even if you only meant to connect.

  • Check visa, e-visa or visa-on-arrival eligibility before booking.
  • You may need arrival cards, customs forms, bag collection and recheck-in.
  • If the first flight is late, the next airline may not protect the connection.
  • Checked bags can be delayed, lost or impossible to retrieve without entering the country.

Flight planning FAQ

Useful questions before booking

Can I book Boise flights from this site?

This is an independent flight guide with booking-search links to travel partners. Final fares, baggage, seat selection and ticket rules are confirmed on the partner site.

Are the airline schedules live?

No static guide can guarantee live schedules. Use the route notes to understand the market, then confirm dates, frequency, terminals and aircraft with the booking partner or airline.

Which booking option should I compare first?

Start with broad flight comparison sites for protected-ticket options, then compare specialist self-transfer engines when price matters and the visa or baggage risk is acceptable.

What should I watch for with separate tickets?

Separate-ticket trips may require entering the transfer country, collecting bags, completing arrival forms and rechecking in, with less protection if a delay causes a missed connection.
