it is her birthday. we have not been offered chairs, water, vouchers, nothing. by this afternoon, the disruption was such that ba took the unusual step of cancelling all flights after 6 from heathrow and gatwick airports. this is the queue for customers leaving the terminal. and there have been reports of severe delays for ba flights around the world. this isjfk in new york. and this is rome. ba said it had experienced an it outage which had affected the airline's global network. it said it was working to resolve the problem and apologised to customers. a senior figure in the aviation industry said an it failure of this magnitude was extraordinary and rarely seen. he added ba had taken the right step to stop all

departures. for some ba passengers though, the long bank holiday weekend could be very long indeed. joe lynam, bbc news. 0n the line is alex woodall, who is at heathrow. i ,and is , and is ineffective. -- tell us how you affected. any delay, a taxi to the gate. i am sorry, we will try to get a better phone line to you. you are breaking up badly. she has been stacked at heathrow having arrived from india. the captain came out to speak to

passengers in rome. all departures cancelled from gatwick until six. i suspect you have plenty of time, unfortunately. we do not have a computer system so you do have at least an hour. it takes about an hour or so. if you want to get refreshments, we will not leave you behind. that is the latest from here in rome. these are passengers waiting for a fight due to leave at

1145 local time. even the british airways staff do not know when the systems failure will come to an end. we are being told that even when the computer system comes back online that the flights at heathrow, a huge backlog of their having to be clear because those guys have not been able to leave for a number of hours now. many sites have landed which have not been able to park. the feeling here is that this could go on for some time yet. shortly after philip sent us pasco, passengers were advised to leave the terminal and find a hotel in the city. 0n the line is lubin reyes betancourt who was due to fly from gatwick airport today. how have you been affected?

how have you been affected ?m how have you been affected? it has been terrible. the lack of information is the consensus among the passengers. when the breaking news came out it was the moment eve ryo ne news came out it was the moment everyone realised that we were not going to five. that is when the lack of transparency the airline became apparent. the breaking news that the flights were cancelled until further notification. it was awful. what has been happening today?” notification. it was awful. what has been happening today? i landed at london heathrow on thursday and have been stuck at gatwick for the play2—mac days. tenerife to the canaries. then, there was chaos on

their side. taking passengers through security. it was full of people. that became a security risk when there was too many to hold in the side of gatwick terminal. what kind of support have you been given in terms of information and refreshments? that is a good question. it is very thin on the ground. also the sheer number of people, it has created huge queues with questions being repeated again and again. lack of information has a lwa ys and again. lack of information has always been the case. the airline industry does not inform its passengers and the passengers no more than they do. where have you

got your information?” more than they do. where have you got your information? i got it from the bbc in terms of the cancellation. passengers within the actual terminal building are engaging with other passengers. it becomes a virtual revival news within the actual terminal. british airways have issued a statement apologising and saying they are sorry for the inconvenience during the holiday period and say they are using airport to munich is in channels and online. how visible have they been? very thin on the ground. you have to also consider the fact that their stress levels must be at their highest. they have no information and are being asked questions by up to 300 people at any one time. they do not know what to

do. the information is very sketchy truly british website. hardly real information to help you as to what your next others. i do not know what is going to happen. imagine the people whose destination was that london, those who were in transit because london was a transit point as they were going towards america, for example. those travelling to cancun. how will british airways jet of those people to cancun when they may not have an american visa? there's passengers which do not, are not allowed to go... this is going to bea not allowed to go... this is going to be a nightmare. those people that do not have this information. not just an apology, it is more than that. it is a next step. the ramifications are many. thank you,

andi ramifications are many. thank you, and i hope you are not stuck there for too much longer. we have alex back on the line. another passenger stuck at heathrow airport. i hope they give you this time. what has happened? i they give you this time. what has happened ? i flew they give you this time. what has happened? i flew in from they give you this time. what has happened? iflew in from delhi they give you this time. what has happened? i flew in from delhi and we took off at 10:30am india time. we landed at three. shortly after landing the captain said we could not taxi to the gates because of a computer systems failure. he has kept us informed, walked around the cabin talking to everyone. even invited people in to have a look at the flight deck. we have been given a drink, one drink, so far. the latest announcement we have heard is that british airways have cancelled everything until midnight but we are not allowed to disembark because the terminal is in chaos, police and everything. we have to wait on the plane and we do not know when we

will be let off. what conditions like? it is a hot day? it is actually quite calm. there is at least one lady on the plane —— baby on the plane. we have a selection of films to watch and things. people seem 0k. films to watch and things. people seem ok. i think if we are here for much longer, that might change. you sounds like you have more information than many in the terminal. how specific are they being with the details? they are not being with the details? they are not being very specific at all. the details about how long we will be waiting keep changing. at first, it was between 30 minutes and one hour. then three hours. now, we do not really know how long. how does this affect your view of british airways as an airline? what is my view? yes,

is it affected? think... i mean, i have always flown. unlike british airways, they try their hardest. i think it is their fault because the captain says he cannot contact anyone to his phone network, it is only through e—mail you can contact the head office or whatever. they are all trying their hardest. how much longer would you be happy to set radio are, just in case anyone has just switched the television on, you are stuck on an aircraft at heathrow! i am exhausted, iwant you are stuck on an aircraft at heathrow! i am exhausted, i want to be at home now. alex, thank you for talking to us. the headlines on bbc news: british airways extends its cancellation of all flights at heathrow and gatwick for the rest

and every one of the 50,000 spectators at radio 1's big weekend in hull will be searched at least once. i got searched twice, once at the transport and once here. no—one minds, because it's all about the safety. i would personally rather wait the extra half hour and get checked. they've got to be there haven't they, that's understandable. although the threat level‘s been reduced, the increased security will continue until midnight on monday. we made the decision that the resources we planned for this week's events will continue, so they'll still see the high level of police presence, some armed, some unarmed. once we are past the weekend, we are going to look forward to stepping down the extra resources we put in place over the last week. georgina callander was killed in the blast. her mum was frantically trying to find her after the concert. today she spoke about the moment that she found her daughter. there she was on the stretcher
