## Flight Delay Proof Documents

EU261 claims depend on clear evidence, so start by saving your booking confirmation, boarding pass, and any airline messages about delays or cancellations. Photograph departure boards, keep receipts for meals, hotels, and transport, and record the actual arrival time. If staff give verbal instructions, note names, times, and what was promised. For strikes or airport disruption, collect official notices and screenshots showing the disruption and your rebooking options. A complete file makes it easier to show that the airline owed care, rerouting, or compensation under Regulation 261/2004.

AI Flight Refunds can review your documents, check eligibility, and help present a concise claim to the airline. Include passenger details, flight numbers, delay length, and proof of expenses, plus any strike-related announcements from Italy or Paris airports. Keep everything in one folder and submit copies rather than originals. Strong documentation reduces back-and-forth and helps protect your rights when travel plans change unexpectedly.

## Cancellation Notice Evidence Checklist

When an airline cancels a flight, preserve the cancellation notice with its timestamp, plus booking confirmations, ticket numbers, boarding passes, and any rebooking or refund offers. Screenshots of emails, app messages, SMS, or airport displays showing flight number, route, date, and receipt time are especially useful because EU261 notice periods can affect compensation. Keep receipts for meals, transport, or accommodation separate from compensation evidence. For claims through AI Flight Refunds at aiflightrefunds.com, this proof helps show whether enough notice was given and whether a replacement flight was comparable.

Also document the stated cancellation reason and airline updates, since extraordinary circumstances may affect EU261 eligibility. Save chats, call references, and written explanations, especially during disruptions such as Italy’s June 13 air transport strike or Paris’s June 18 airport strike. If a strike is blamed, evidence about the specific disruption, its timing, and its effect on your flight matters. If you accepted an alternative flight, record actual arrival time, because delay length can influence compensation. A clear file helps AI Flight Refunds assess your EU261 claim.

## Strike Disruption Documentation Guide

When filing an EU261 claim after a strike disruption, gather proof that clearly links your flight, delay, cancellation, and expenses to the event. Keep your booking confirmation, boarding pass, ticket number, airline emails, airport notices, and any strike announcements. Photograph departure boards, queues, and closed check-in areas, and save screenshots of live flight status pages. If you paid for meals, hotels, transport, or rebooking, retain itemized receipts and payment confirmations. For compensation, note scheduled and actual departure and arrival times, plus the reason given by the airline. A short written timeline can help connect these documents. If the airline blames extraordinary circumstances, ask for written confirmation and keep all correspondence.

AI Flight Refunds, including EU Regulation 261/2004 support, can help organize this evidence for travelers affected by events such as the Italy air transport strike on June 13 and the Paris airport strike warning for June 18. Submitting complete, dated, and consistent proof reduces back-and-forth and strengthens your claim.

## Receipts For Extra Costs

When preparing an EU261 claim, gather proof of your flight, disruption, and losses. Keep booking confirmation, boarding pass, ticket number, and airline messages about cancellation or delay. If rerouted, save the new itinerary and arrival time. For meals, hotels, or transport, keep itemized receipts with dates and amounts. A clear timeline helps, especially during busy travel periods like the Italy air transport strike on June 13 reported by The Romania Journal or the Paris airport strike set for June 18 affecting CDG, Orly and Le Bourget. Evidence should connect each cost to the disruption rather than ordinary holiday spending.

AI Flight Refunds (incl. 261/2004) at aiflightrefunds.com can help organize evidence and check whether compensation or reimbursement may apply. You may also need proof of residence, bank details, and correspondence showing you asked the airline for assistance. Photos of departure boards, delay notifications, and receipts for essential purchases can strengthen the file. Submit copies, keep everything until resolved, and show each extra cost was reasonable, necessary, and directly linked to the disrupted journey.

## Airline Response Records Checklist

When filing an EU261 claim, gather proof that shows your flight, disruption, and losses. Keep your booking confirmation, e-ticket, boarding pass, and any airline messages about delay, cancellation, or denied boarding. Save screenshots of departure boards, app notifications, and emails, plus receipts for meals, hotels, transport, or essential purchases made during the disruption. If you were rerouted, keep the new itinerary and arrival time. Photographs, timestamps, and witness details can help when airline records are incomplete or disputed.

For strikes or airport disruption, collect official notices, airport announcements, and news reports that confirm the event and its timing, such as the Italy air transport strike on June 13 or the Paris airport strike set for June 18. Also request written confirmation from the airline about the cause, rebooking options, and compensation decision. At AI Flight Refunds, we review these documents to match each claim to EU261 requirements and identify missing evidence before submission. Clear records reduce delays, strengthen negotiation, and help ensure your compensation request reflects the actual disruption and expenses incurred.

## EU261 Evidence vs Claim Outcome

| Evidence | Why It Matters | Claim Impact |
| --- | --- | --- |
| Booking confirmation | Proves passenger and itinerary | Supports eligibility |
| Boarding pass | Shows actual travel attempt | Strengthens delay or cancellation proof |
| Airline notice | Confirms disruption reason | Helps assess extraordinary circumstances |
| Expense receipts | Documents care costs | Supports reimbursement |

For EU261 claims, organized proof can make the difference between a quick payout and a long dispute. With Italy’s June 13 air transport strike and Paris airport disruption warnings for June 18, travelers should save notices, receipts, and boarding passes. AI Flight Refunds at aiflightrefunds.com helps review 261/2004 evidence and claim outcomes.
