I completed my 16 Iberia sectors over the last 3 days. To add to neelcor 's list in #4

Steps from aircraft, walk into the baggage claim, re-clear security. B2B time: ~ 5 minutes

• SDR - Santander (A320), CDT - Castellon (CRJX), GRX - Granada (CRJX).
• All small airports with minimal other flights and was back at the gate comfortably before boarding started.

Arrive straight into departures. B2B time: Instant

• Airbridge: MAD - Madrid (A32x), VGO - Vigo (A320), IBZ - Ibiza (A321), PMI - Palma (A320)
• Walk/Bus: MAD - Madrid (CRJX)
• At IBZ, the rear door was also used. Passengers disembarked into a bus via stairs, but don't know where that went.

Staff Assisted

• Airbridge: BIO - Bilbao (A321).
• Slightly strange set up. The airbridge led to an arrivals stream with signs to baggage reclaim/connections. However, the same area also had the BP scanner to board the departing passengers. I could see the departing passengers in an area through a glass door, so I advised the staff I was doing a B2B and they allowed me to wait at the gate.B2B time: Instant.
• I still would have had enough time to reclear security as boarding didn't start for 15 mins and then took ages because of being a full A321.

I'll update on crediting over on the RJ forum.
