Why is the advertised fare not the real price?

Airlines — especially on basic economy and ultra-low-cost carriers — unbundle the fare. The headline price often excludes checked bags, carry-ons, seat selection, and change fees. Add them up and the 'cheap' fare can cost more than a standard one.

How accurate are these fee estimates?

The calculator uses representative fee levels for legacy, low-cost, and ultra-low-cost carriers. Exact fees vary by route, date, elite status, and how you pay, so treat the total as a close estimate for comparing options — not an exact quote.

How do I avoid these fees?

Compare the all-in price, not the headline fare; consider a standard economy fare that bundles a bag; and check whether a co-branded card or elite status waives bag fees. Planet shows the effective cost after cashback so you can compare like for like.

The fare you see is rarely the price you pay. Add bags, a carry-on, seat selection, and any changes to reveal the true all-in cost of a flight — and exactly how much the extras pile on.

Why “cheap” fares often aren't

Unbundling is how the lowest headline fares get built. On an ultra-low-cost carrier, a $59 fare can turn into well over $200 round trip once you add a carry-on, a checked bag, and a seat — sometimes more than a standard economy ticket that includes all of it. Basic economy on legacy airlines plays the same game with change restrictions and last-to-board seating.

The fix is simple: compare the all-in price, not the teaser. Planet goes one step further and shows your effective member cost after cashback, so two fares are finally comparable on the number that matters — what actually leaves your wallet.
