What is the situation in case of emergencies when oxygen masks drop: I assume, there is one per pax seat, but what is the situation for example when there are two infants / two adults in an F-100 on the side where you have only two seats: There are not enough 02 masks for 4 persons.
Are there any previsions on airliners for seats/seatrows with extra masks forseen in case infants accompany their parents and share their seats?

I fly on the E-170 which is a 2x2 configuration in economy, 1x2 in First Class.
We have 3 oxygen masks on each side of the aisle, a total of 6 per row. We only allow one lap child per two seats, so in any given row there can only be two lap children at most, and no more than one on either side of the aisle. That way everyone has a mask.

US registered commercial aircraft that fly high enough to require oxygen must comply with 14CFR25.1447, which states, in part:
"The total number of dispensing units and outlets in the cabin must exceed the number of seats by at least 10 percent. The extra units must be as uniformly distributed throughout the cabin as practicable."

In addition, most airlines carry extra hand-held O2 tanks that are meant for the flight attendents, but can also be used in a scenario such as you described. One thing is for sure, "you should secure your mask before securing those of those around you."

The handheld oxygen bottle for sure will be abandoned in emergencies when everybody - including crew - will gasp for air and grab onto something firm and not wander around asking who needs a sip of oxygen.

Interesting info, thanks for feedback. So, on an A-380 this will mean there will be more reserve oxygen masks than seats on many RJ's!

I depends on the aircraft type. ive been checking in for thomas cook at MAN all summer, and it varied from boeing to airbus. For example, on a 757 only 1 infant is allowed on every set of 3 seats. So if a couple has two infants, they are given seats either side of the aisle. On the 320, there is only 1 extra oxygen mask per row, which alternates sides on each row. For example, on row 1, the extra mask would be located with seats ABC, but on row 2, it would be located with seats DEF.

Our procedures are;
The cabin crew will grab the nearest drop down mask to where they are. If they are in the aisle, they will either sit on your lap or wedge themselves between the seats until the inital emergency descent is completed. We will normally get a PA from the flight deck announcing inital descent complete. Then we do the monkey swing moving from mask to mask until we reach a portable oxygen set. Once that's fitted, we then go through the cabin assessing aircraft damage and passenger condition before reporting to the senior crew member who feeds all our observations to the flight deck. We only remove our masks once given the OK by the flight deck. Note - when the masks fall, everyone looks out for themselves, so don't expect a crew member to help you with the mask!
We have one aircraft in our fleet that only has 4 masks on the ABC side. The number of times we've delayed departure because check in have ignored the aircraft config and seated an infant in the DEF side! The drop down oxygen lasts a minimum of 12 minutes and when operated will smell of burning due to the chemical generator.

The infos posted here are so important I wonder why they are not mentioned on the aircraft because for example when a pax wanders around the aisle when an emergency occurs, it would be important that he knows these vital informations/indications.
Personally I have flown a lot and never knew the info from the feedback: In regards of onboard safety, please add any other smart infos to this post!
