Yes, very good point which is probably why the airline's original press release must've contained the following word-for-word excerpt, because all four articles have copied it into theirs:

I got so caught up with the idea of using my iPhone for eight hours online, alongwith the two hours to the airport and the two hours at the airport that I forgot to think of this very real possibility. And my flight to Oman is right through the night. Nothing worse than a bunch of loud mouthed Asians... though if they're speaking in Tamil it gives me a chance to catchup on all the words I've forgotten over the Winter and Spring!
