Who is affected by the new rule from 25 February?

British dual citizens are affected. If you hold UK citizenship and another nationality, you must travel to the UK on a UK or Irish passport, or carry a £589 certificate of entitlement. Other passports or proof of status are not sufficient under the new UK border rules.

What documents will airlines accept at check-in?

Airlines will accept a valid UK or Irish passport. If you do not have one, they will look for a certificate of entitlement that costs £589. Without either, staff must deny boarding under the policy. Bring the physical document. Digital confirmations are unlikely to replace it.

Will this cause airline cancellations in the UK?

Most effects will be denied boardings and delays. However, if loads fall or turnarounds slip, some operators may consolidate flights, which can appear as airline cancellations. Investors should track same-day schedule changes, on-time performance, and refund announcements in the first week of enforcement.

Do passengers get compensation if they are denied boarding?

Usually not. Under UK261, compensation typically does not apply when a passenger lacks required travel documents. You may still receive a refund or rebooking per fare rules or goodwill. If staff misapply the rule, escalate with the airline promptly and keep written evidence of eligibility.
