If anyone has booked a package through the holiday place and didn't receive their atol certificate you should still be able to claim. The CAA knows the holiday place were bonded and when you fill out their claim form you send your invoice, proof of payment, booking confirmation. You can claim 100% back. If not a package but did book flights and accommodation just not on same day so classed as flight plus you can also claim. For accommodation only, try your credit card.
