Collecting Avios is easy. Spending them well is the part that trips people up — and a new guide for first-time collectors lays out the classic errors, from hoarding points to booking 'free' flights that cost a fortune in fees.

The biggest trap, according to the piece, is earning without a goal. It's tempting to chase every sign-up bonus and shopping promotion until you're sitting on 100,000 or 200,000 Avios with no idea what to book. The suggested fix: work backwards from a rough trip — destination, dates, cabin, who's coming — and only pursue earning offers that serve it.

Value is the second big theme. Not every redemption is a good deal, and the maths is simple enough to do yourself: take the cash price you'd otherwise pay, subtract the taxes and fees you'll still owe, divide by the Avios spent. A £500 flight booked for 25,000 Avios plus £100 works out at 1.6p per point — strong. A £150 fare for 20,000 Avios plus £50 gives just 0.5p, which is weak. Around 1p per Avios is a reasonable benchmark. And Business Class isn't automatically the smart play; if the premium seat costs vastly more points plus a hefty surcharge, a well-priced Economy redemption you actually want beats it.

On fees: reward flights are never truly free. Taxes and carrier charges can hit hundreds of pounds on long-haul premium cabins, though British Airways' Reward Flight Saver can shrink the cash component dramatically — from as little as 50p per leg on short-haul European routes, or £1 return.

Availability is where beginners get burned. Having the points doesn't guarantee a seat. BA guarantees at least 14 reward seats per flight and opens bookings 355 days out; Iberia opens at 360 days but promises no minimum. The advice is to search early, keep checking (inventory shifts constantly as bookings are made and cancelled), and set alerts with a reward flight finder rather than searching once and giving up.

A few more habits worth avoiding: don't transfer flexible points like Amex Membership Rewards or Nectar into Avios before you've picked a redemption — transfers can be irreversible, and you may miss transfer bonuses along the way. Don't sign up for every card and promotion you see; annual fees, minimum spends and voucher expiry dates pile up fast, and you should never carry credit card debt to earn points. Do check what comes with an Avios credit card beyond the points — BA Amex cards can offer Companion Vouchers, while Barclaycard's Avios cards offer Upgrade Vouchers, both valuable if used well. Remember that flying isn't the main way most people earn: everyday spending routed through cards and shopping partners does the heavy lifting. And don't hoard forever — programmes devalue, and a stockpile sitting unused isn't an achievement.

Who's this for? Anyone in the UK (or flying BA, Iberia or partner airlines) starting out with Avios, or sitting on a balance they've never redeemed. The core lesson: plan a redemption first, earn second, and always price the cash alternative before you click book.
