You can see list of supported video formats, when open the drop-down list of file types near the bottom of the Insert Movie and Sound dialog box. I have no problem with playing video of different formats in my LibreOffice Impress. I suggest you install last codec pack, for instance K-Lite Codec Pack. edit delete.
The rules are the same for paid tickets. American Airlines Canceling an award ticket costs $150 for the first award, and $25 for each additional award reinstated at the same time for the same account. Thereâs no fee to change an award ticket, so long as the origin and destination remain the same.
On American, the $150 change fee would be deducted from the price of your original fare, and you would have a credit voucher of $350. Here's the other sad part about US Airways policies. Let's say you do pay your $200 change fee and your new ticket costs $200. Under this policy, you would lose the remaining $100. On American and Delta, if the new ticket costs $200, you get the rest after the change fee is deducted.
